NCERT Solutions Class 10 Science Book All Chapters:

Chapter 1 – Chemical Reactions and Equations

Students will learn about chemical reactions, how to construct equations, how to conduct combination and decomposition reactions, and more in the first chapter of Class 10 NCERT Science. We have studied about the chemical and physical transformations of matter in earlier classes. We can refer to any change in composition that takes place as a chemical reaction. A full chemical process symbolically depicts the reactants, products, and their physical states. In addition, the art of writing a chemical reaction—a symbolic depiction of a chemical reaction—will be taught to the students. The chapter also describes the multiple states in which distinct chemical equations can be balanced.

The next subtopic includes a variety of examples and chemical reactions to teach about many types of reactions, including combination, decomposition, displacement, and double displacement processes. Exothermic and endothermic reactions are discussed in terms of energy. Reactions that release heat along with their products are called exothermic reactions; on the other hand, reactions that absorb energy are called endothermic reactions. The explanation of redox reactions follows, which are a combination of oxidation and reduction reactions. All types of reactions are explained in this chapter along with appropriate examples and the corresponding chemical equations.

Chapter 1 of Class 10 Science: Chemical Reactions and Equations Covered Topics

Chemical equations, balanced chemical equations, the implications of a balanced chemical equation, and the various types of chemical reactions—including oxidation, reduction, displacement, double displacement, precipitation, endothermic and exothermic processes, combination, decomposition, and displacement—are all discussed here.

Chapter 2 – Acids, Bases and Salts

Salts, bases, and acids are the main topics of NCERT Class 10 Science Chapter 2. Students have studied in the past that the presence of bases and acids in food causes its sour and bitter flavours. As is common knowledge, bases are bitter and turn red litmus blue, while acids have a sour taste and turn blue litmus red. This chapter will cover a variety of fascinating topics that are relevant to everyday life, such as the interactions that occur between acids and bases and how their effects cancel each other out.

After giving a relevant example to illustrate what all acids and bases have in common, the chapter concludes that an acid solution in water conducts electricity. By using universal indicator, students can learn about a variety of experiments that explore what happens to an acid or a base in a water solution and how powerful acid or base solutions are. Students will also study about the significance of pH in daily life in conjunction with it. A thorough discussion of salt’s manufacture, characteristics, and applications concludes the chapter.

Chapter 3 – Metals and Non-metals

Students must have studied about the different elements that, depending on their characteristics, might be categorised as metals or non-metals in earlier classes. Students will learn about the physical characteristics of metals and non-metals in this chapter of Class 10 Science. In addition to being glossy, malleable, and ductile, metals are effective heat and electrical conductors. Mercury is a liquid at normal temperature, while the others are solids. Metals’ physical characteristics are explained by a number of factors, including their strength, malleability, tensile nature, and ductility. Metals are distinguished from non-metals based on their physical attributes. Non-metals include, among other things, carbon, sulphur, iodine, oxygen, hydrogen, and so on. All non-metals, with the exception of bromine, which is a liquid, are either solids or gases. The subtopic “Chemical Properties of Metals” discusses chemical reactions involving water, acids, oxygen gas, and other metal salts. The reactivity series determines the conditions and reactions. Gold is the least reactive metal in the reactivity series, whereas potassium is the most reactive.

Ionic or electrovalent compounds are those created in this way when electrons are transferred from a metal to a non-metal. Ionic compounds have a variety of general characteristics, including physical composition, solubility, melting and boiling points, and electrical conduction. Metallurgy is the process of extracting metal from its ore and then purifying it for usage. The electrolytic refining method is used to refine metals. Corrosion is explained and prevented in the final topic.

Chapter 4 – Carbon and its Compounds

Prior to this chapter, we covered chemicals that were significant to us. We will examine a few more intriguing compounds and their characteristics in this chapter. We will also study about carbon, an element that is extremely important to us in both its elemental and compounded forms. Almost everything that is alive and most of the items we use are made of the versatile element carbon. Two atoms share electrons to form covalent bonds, which allow them to reach a fully filled outermost shell. Together with other elements like hydrogen, oxygen, sulphur, nitrogen, and chlorine, carbon also forms covalent bonds with itself. Saturated and unsaturated carbon compounds are the two types of organic molecules.

A few of the chemical characteristics of carbon and its compounds, including combustion, oxidation, addition, and substitution reactions, are also explained in this chapter. In our daily life, carbon molecules such as ethanol and ethanoic acid are significant. The chemical structures and characteristics of soap and detergents are examined, and their distinctions are also covered. Shampoos and laundry detergents are typically made from detergents.
Chapter 4 of Science for Class 10 covers the following topics:

Carbon compounds: Carbon compounds include covalent bonds. The adaptability of carbon. similar series. Naming conventions for carbon compounds with functional groups (alcohol, ketones, aldehydes, alkanes, and alkynes), with emphasis on the distinctions between unsaturated and saturated hydrocarbons. Carbon compounds’ chemical characteristics (combustion, oxidation, addition, and substitution reactions). Soaps and detergents, ethanol and ethanolic acid (only characteristics and uses).

Chapter 5 – Periodic Classification of Elements

We have learnt in Standard 9 that matter exists all around us in the forms of elements, compounds, and mixes, with elements consisting of atoms of a single type. When the elements were first classified, they were divided into two categories: metals and non-metals. Newlands provided the

Law of Octaves, whereas Dobereiner categorised the elements into triads. Mendeleev grouped the elements based on their chemical characteristics and ascending order of atomic mass. He even used gaps in his Periodic table to anticipate the emergence of several elements that have not yet been found. The periodic table as we know it now was created. The Modern Periodic Table was created using the atomic number as the foundation and amended Mendeleev’s Periodic Law.
The elements in the Modern Periodic Table are grouped in seven horizontal rows, or periods, and eighteen vertical columns, or groups, as described in this chapter, Periodic Classification of Elements. When elements are grouped in this way, they display periodic features such as metallic and non-metallic character, valency or combining capability, and atomic size. The quantity of valence electrons in an element’s outermost atomic shell determines its valency. The radius of an atom is referred to as its “atomic size.”

Chapter 6 – Life Processes

Chapter 6 of NCERT Science for Class 10 discusses Life Processes. Every living thing engages in six basic life processes. These include breathing, growing, reproducing, excreting waste, and feeding. The chapter also covers nutrition, which is the process of ingesting food and using it for metabolism, development, and repair. Ingestion, digestion, absorption, transport, assimilation, and elimination are the phases involved in nutrition. Heterotrophic and autotrophic nutrition are further subdivided under nutrition. Simple inorganic elements from the environment are consumed in autotrophic feeding, while complex, high-energy organic components are synthesised utilising an external energy source, such as the sun. Heterotrophic nutrition refers to consuming complex food that has been produced by another organism. Holozoic, saprophytic, and parasitic nutrition are three distinct forms of heterotrophic nutrition.

The subject of human nutrition will be covered next. Ingestion, digestion, oesophagus, stomach, small intestine, bile, absorption, assimilation, and egestion are the several stages of nutrition. The next subtopic is respiration, which provides a lovely explanation of the human respiratory system. The human respiratory system is made up of various parts, such as the lungs, bronchi, larynx, and throat. Organic substances like glucose are broken down to produce ATP, which is used as energy during respiration. The energy for subsequent processes in the cell is derived from ATP.

Aerobic or anaerobic respiration is possible. The organism has access to additional energy thanks to aerobic respiration. The closest and most abundant source of minerals, such as phosphorus and nitrogen, for plants is the soil. The circulatory system in humans is responsible for moving substances like food, oxygen, carbon dioxide, and excretory products. The blood, blood arteries, and heart make up the circulatory system. Water, minerals, food, and other elements are transported by highly specialised plants’ vascular tissue, which is made up of xylem and phloem. Nephrons in the kidneys of humans eliminate excretory products in the form of soluble nitrogen molecules. Plants eliminate waste using a multitude of methods.

Chapter 7 – Control and Coordination

In Class 10, Chapter 7, we learn about the roles that our bodies’ hormones and neurological system play in providing us with control and coordination. It is possible to categorise the neurological system’s reactions as reflex, voluntary, or involuntary. Electrical impulses are used by the neurological system to send messages. It functions through our muscles after gathering data from our sense organs. Coordination of chemicals is observed in both plants and animals. To accomplish their intended purpose, hormones generated in one area of an organism transfer to another. Hormone action is regulated by a feedback system.

Chapter 8 – How do Organisms Reproduce

Reproduction is not necessary, in contrast to other life processes, for an individual organism to survive. How Do Living Things The reproduce chapter describes how the cell that is participating in the process makes a copy of its DNA and adds more cellular machinery. Different species employ different techniques of reproduction depending on how their bodies are designed. Many bacteria and protozoa simply split into two or more daughter cells during fission. If an organism is split into fragments, it can regenerate, just like a hydra. They are also capable of producing buds that develop into new people. Through vegetative propagation, certain plants can produce new plants from their roots, stems, and leaves. These are instances of asexual reproduction, in which a single individual gives rise to new generations.

Pollination, the process by which pollen grains are transferred from the anther to the stigma during flowering plant reproduction, is known as such. The process of fertilisation comes next. Puberty-related physical changes, such as a rise in breast size in girls and the development of new facial hair in boys, are indicators of sexual maturation. The testes, which generate sperm, the vas deferens, seminal vesicles, the prostate gland, the urethra, and the penis make up the male reproductive system in humans. The human female reproductive system is comprised of the uterus, vagina, fallopian tubes, and ovaries. In humans, sexual reproduction entails the insertion of sperm into the female’s vagina. The fallopian tube is the site of fertilisation. Condoms are a method of contraception that can be used to prevent pregnancy.

Chapter 9 – Heredity And Evolution

We shall study heredity and evolution in this chapter. Reproductive mechanisms have been shown to produce comparable but slightly different offspring. We have talked about how even in asexual reproduction, variety is produced to some extent. The idea that virtually equal amounts of genetic material are passed down to children from both parents is covered by the Rules for the Inheritance of Traits in Humans. This implies that both maternal and paternal DNA can have an impact on any given trait. In different animals, there are distinct factors that determine sex. Environmentally induced changes to non-reproductive tissues are not heritable. When variation is paired with geographic isolation, speciation may occur.

Fossils as well as extant animals can be studied to learn more about evolution. The advantage of even the intermediate phases for survival may have led to the evolution of complex organs. During evolution, organs or characteristics may adapt to take on new roles. It is impossible to claim that evolution moves from lower forms to higher forms. Instead, it appears that evolution has led to the emergence of increasingly intricate body shapes, even while simpler body patterns persist. Human evolution research shows that we are all members of a single species that originated in Africa and gradually expanded around the globe.

Chapter 10 – Light Reflection and Refraction

Using the straight-line propagation of light, we shall examine the phenomena of reflection and refraction in NCERT Class 10 Science Chapter 10. We can better understand some of the optical phenomena in nature by using these fundamental ideas. The chapter also covers light refraction and its practical applications, such as light reflection from spherical mirrors. Light is an energy source that gives humans the perception of vision. It appears like light moves in straight lines. Students learn about the two types of spherical mirrors: convex and concave. Ray diagrams are used to discuss the different terminology associated to spherical mirrors, such as focus, pole, radius of curvature, etc.

When a wave enters a medium where its speed is different, it bends, a phenomenon known as refraction. When light moves from a fast medium to a slow medium, it refracts, bending its rays in the direction of the normal to the boundary between the two media. The notions of refractive index and optical density facilitate an easy understanding of the phenomenon of refraction. The ratio of the speed of light in a vacuum to that in the medium is known as the refractive index of a transparent medium. Refraction occurs at the glass-air interface as well as the air-glass interface in the case of a rectangular glass slab. The direction of the emergent ray is parallel to that of the incident beam.

Chapter 11 – The Human Eye and Colorful World

Some of the properties of light were covered in the previous chapter. We shall examine a few of the optical phenomena found in nature in this chapter. The creation of rainbows and the division of blue and white light in the sky are also covered in this chapter. One of the most vital and delicate sense organs in the human body is the eye. We can see the beautiful world and the colours all around us thanks to it. The accommodation of the eye refers to its capacity to focus on both close and far objects by varying its focal length. The near point of the eye, also known as the least distance of distinct vision, is the minimum distance at which the eye can see objects clearly and strain-free.

The three most prevalent refractive errors in eyesight are presbyopia, hypermetropia, and myopia. Myopia, or short sight, is a condition in which the retina is corrected by using a concave lens of the appropriate power after the image of far-off objects is focussed. With a convex lens of the appropriate power, hypermetropia (farsightedness, where the picture of close objects is focused beyond the retina) can be rectified. As we age, our eyes lose their ability to adapt. Dispersion is the process of breaking down white light into its constituent hues. The blue hue of the sky and the reddening of the Sun during sunrise and sunset are caused by light scattering.

Chapter 12 – Electricity

Modern society relies heavily on electricity. It is a practical and controllable energy source that may be used in a range of settings, including homes, businesses, schools, and hospitals. It is an occurrence connected to charge flow. An electric current is a stream of electrons flowing through a conductor. Traditionally, current flow is measured in the opposite direction to that of electron flow. Ampere is the SI unit of electric current. We utilise a cell or a battery to move the electrons in an electric circuit. A potential difference is produced between the terminals of a cell. Volts (V) are used to measure it. A conductor’s ability to thwart the flow of electrons is known as resistance.
It regulates the current’s strength. Ohm is the SI unit of resistance. According to Ohm’s law, if a resistor’s temperature doesn’t change, the potential difference across its ends is directly proportional to the current flowing through it. A conductor’s resistance is directly influenced by its length, inversely by its cross-sectional area, and also by the conductor’s substance. When many resistors are connected in series, their total resistance equals their equivalent resistance. W=V x I x t gives the electrical energy dissipated in a resistor. Watts is the unit of power (W). When 1 A of current flows at a potential difference of 1 V, one watt of power is consumed.

Chapter 13 – Magnetic Effects of Electric Current

Students will learn about electromagnetic phenomena such as magnetic fields in this chapter. They will also learn about electric generators, which use the electric effect of moving magnets, and electromagnets and electric motors, which use the magnetic effect of electric current. A little magnet is what a compass needle is. Its north pole is the end that points in that direction, and the south pole is the end that points in that direction. The area around a magnet has a magnetic field that allows one to measure the magnet’s force. A magnetic field is represented by field lines. A hypothetical free north pole’s natural course is called a field line. Where there is a stronger magnetic field, field lines are displayed closer together. A magnetic field is connected to a metallic wire that is conducting an electric current. The right-hand rule determines the direction of the concentric circles that make up the field lines surrounding the wire. The form of a conductor determines the pattern of the magnetic field that surrounds it when an electric current passes through it.

A solenoid that is conducting current has a magnetic field that resembles a bar magnet’s. A coil of insulated copper wire is wrapped around a soft iron core to form an electromagnet. A current-carrying conductor feels force when it is in a magnetic field. The force acting on the conductor will be perpendicular to both if the current and the field are both directed in the same direction. This force can be found using Fleming’s left-hand rule. This is how an electric motor works. An apparatus that transforms electric energy into mechanical energy is an electric motor.

The creation of induced current in a coil situated in an area where the magnetic field fluctuates over time is known as electromagnetic induction. The relative velocity of a magnet positioned close to the coil and the coil itself may cause changes in the magnetic field. When a coil is positioned close to a conductor that carries current, the magnetic field may shift as a result of the current flowing through the conductor or as a result of the coil and conductor moving relative to one another.

With Fleming’s right-hand rule, the direction of the induced current is determined. Electrical energy is produced from mechanical energy by a generator. Electromagnetic induction is the basis for its operation. Generators come in two varieties: AC and DC. The most crucial safety device is the fuse, which guards against overloading or short circuiting circuits.

Chapter 14 – Sources of Energy

Our standard of living rises along with our energy needs. We work to increase energy consumption efficiency and explore new energy sources in order to meet our energy needs. The chapter covers many energy sources, all of which are traditional energy sources that humans have been using for a long time. It consists of thermal power plants, hydroelectric plants, and fossil fuels. The benefits and drawbacks are also covered. Following those technological advancements, the use of traditional energy sources like wind and biomass is also covered. The subject of non-conventional or alternative energy sources will be covered by the students after this.

In NCERT Solutions Class 10 Science Among them is solar energy, which is produced by solar panels and solar cells. The ocean can produce various forms of energy, including wave, tidal, and thermal energy. Geothermal energy is another source of energy that can be produced from the earth’s crust. Energy found in an atom’s nucleus, or core, is known as nuclear energy. The energy source we choose will be determined by a number of criteria, including how simple and expensive it is to extract energy from the source, how effective the technology is for doing so, and how using the source will affect the environment. In the end, the Sun provides energy to a large number of the sources. Each issue is covered along with its benefits and drawbacks.

Chapter 15 – Our Environment

This chapter explores our interactions with the environment and how different elements work together. An ecosystem’s different parts are interrelated. The producers provide the rest of the ecosystem with sunlight energy. The number of trophic levels in a food chain is constrained by the energy lost as one moves up the trophic ladder. Using real-world examples from the forest, grassland, and pond, the food chain is thoroughly presented.
The environment is impacted by human activity. The ozone layer is in risk due to the usage of chemicals like CFCs. Since the ozone layer shields the Earth from solar UV radiation, this could be harmful to the ecosystem. We may produce biodegradable or non-biodegradable garbage. There are major environmental issues resulting from the way we dispose of the waste we produce.
