NCERT Solutions Class 10 Science & Main Points of All Chapters
Chapter 1: Chemical Reactions and Equations
Class 10 Science Chapter 1 deals with the various types of Chemical Reactions and Equations with related examples. It also teaches how to write a skeleton reaction and way to balance the chemical reactions. There are mainly five kinds of reactions which are combination reaction, Decomposition reactions, Displacement and Double Displacement reactions and Oxidation-Reduction or Redox reactions. The introduction with the example of exothermic and endothermic reactions are also important for board exams. We can learn here about how precipitation reactions produce insoluble salts.
Chapter 2: Acids, Bases and Salts
Class 10 Science Chapter 2 includes the concepts of Acid-base indicators or mixtures of these dyes which are used to indicate the presence of acids and bases. The concentration of H+ ions and OH- ions are the base for the concepts of Base or Acids. Further, we have to study the reactions of Acids or Bases with Metal, Water and Metal Carbonates also. The properties of acidic and basic solutions in water are given on a separate segment. The strength of an acid or an alkali can be tested by using a scale called the pH scale (0-14) which gives the measure of hydrogen ion concentration in a solution. The crystallisation of compounds with water is the fixed number of water molecules present in one formula unit of salt. There are various uses of salts in everyday life and in industries.
Chapter 3: Metals and Non-Metals
In Chapter 3 of Class 10 Science, we will study that elements can be classified as metals and non-metals. We will go through the physical and chemical properties of metals and non-metals. Physical properties of metals are lustrous, malleable, ductile and are good conductors of heat and electricity. There are some exceptions like metals are solid at room temperature but mercury which is a liquid. Few metals show the properties of both basic as well as acidic oxides. These oxides are known as amphoteric oxides. The main topics of Class 10 Science Chapter 3 are Activity series, Ore, Mineral, Gangue, Extraction of Metals from their ores, Metallurgy, Alloy, Corrosion and Rancidity.
Chapter 4: Carbon and its Compounds
Chapter 4 of Class 10 Science, covers deals with versatile properties of carbon, Catenation and Tetravalency. Formation of Single, Double and Triple Covalent Bonds by the sharing of the electron. Carbon compounds with straight chains branched chains or rings. Knowledge about homologous series of compounds and functional group attached to carbon chains such as alcohols, aldehydes, ketones and carboxylic acids. Preparation of Ethanol with proper Chemical Reactions and properties of Ethanol and ethanoic acid, The action of soaps and detergents with the concepts of hydrophilic or hydrophobic groups.
Chapter 5: Periodic Classification of Elements
Class 10 Science Chapter 5 is based on how elements are classified on the basis of similarities in their properties. Elementary knowledge about Döbereiner’s triads and Newland’s Law of Octaves. Merits and drawback of Mendeléev periodic table and the contribution of this table in the discovery of new elements. Modern periodic table proposed by Henry Moseley. Physical and chemical properties trends in the modern periodic table. We have to learn about Periodicity which is the properties including atomic size, valency as well as combining capacity and metallic and non-metallic character.
Chapter 6: Life Processes
Life processes include the main four processes like Nutrition, Digestion, Respiration and Excretion. We know that maintenance of life requires these processes to transport of materials within the body and excretion of waste products. Autotrophic nutrition and Heterotrophic nutrition both describe separately. In human beings, the food eaten is broken down by various steps along the alimentary canal and the digested food is absorbed in the small intestine to be sent to all cells in the body. Respiration may be aerobic or anaerobic. Aerobic respiration releases more energy as compared to anaerobic. In human beings, excretory products in the form of soluble nitrogen compounds whereas in plants gum and resin.
Chapter 7: Control and Coordination
Control and coordination, in Class 10 Science, have the functions of the nervous system and hormones
in our bodies. The responses of the nervous system as a reflex action, voluntary action or involuntary action. Functions of sensory and motor nerves. The nervous system uses electrical impulses to transmit messages using neurons. Chemical coordination in plants using various hormones. Effect of hormones and related glands in human. The action of the hormones is totally based on a feedback mechanism.
Chapter 8: How do Organisms Reproduce?
Class 10 Science Chapter 8 involves the creation of a DNA copy and additional cellular apparatus by the cell involved in the process and different modes of reproduction depending on their body design. For example, in fission, many bacteria and protozoa simply divide into two or more daughter cells, whereas organisms such as hydra can regenerate if they are broken into pieces. Roots, stems and leaves of some plants grow to be new plants through vegetative propagation. Sexual Reproduction is totally different from Asexual Reproduction. Sexual reproduction involves two individuals for the creation of a brand new individual. Reproduction in flowering plants involves the transfer of pollen grains from the anther to the stigma which is referred to as pollination. Sexual reproduction in human beings involves the introduction of sperm to fertilisation occurs in the fallopian tube.
Chapter 9: Heredity and Evolution
Variations arising during the process of reproduction can be discussed in Chapter 9 Heredity and Evolutions of Class 10 Science. As we know that sexually reproducing individuals have two copies of genes for the same trait. Concepts of dominant trait and recessive trait traits describe the transfer of traits properly in this chapter. Difference between inherited and acquired traits are the important topics which are frequently asked in Boards. The determination of sex of the offspring depends on different factors in all species. All the variations during the reproductions in the species somehow confer survival advantages. Sometimes it also shows the genetic drift. Due to geographic isolation, the speciation of species takes place.
Chapter 10: Light – Reflection and Refraction
In Class 10 Science Chapter 10 Light and related phenomena, Reflection or Refraction are given in brief. The concepts given in Light chapter are also important for further classes. The straight-line path of light and mirror – lens application is given for study. We have to study the reflecting surfaces, of all types, obey the laws of reflection and the refracting surfaces obey the laws of refraction. Main topics are New Cartesian Sign Conventions, mirrors and lenses formula, focal length, the radius of curvature and magnification. The power of a lens is measured as the reciprocal of its focal length. Its SI unit is dioptre.
Chapter 11: Human Eye and Colourful World
After going through Chapter 11 of Class 10 Science, we will be able to know about the accommodation of the eye, the near point of the eye or the least distance of distinct vision. The common defects of vision, which are included in Class 10 Science Chapter 11, are myopia, hypermetropia and presbyopia. Myopia. The splitting of white light into seven colours (VIBGYOR) is called dispersion. We will study here how to form a Rainbow or why we see sky reddish in the morning or evening. The blue colour of the sky and the reddening of the Sun at sunrise and sunset is due to scattering of light.
Chapter 12: Electricity
We will deal here with the basic concepts of Electricity and its heating effects. We know that a stream of electrons moving through a conductor constitutes an electric current. But, conventionally, the direction of current is taken opposite to the direction of flow of electrons. In Chapter 12 of Class 10 Science, we will learn about the SI unit of electric current, use of a cell or a battery and use of voltmeter and ammeter. The main topic is Ohm’s law which states that the potential difference across the ends of a resistor is directly proportional to the current through it, provided its temperature remains the same. Concepts of resistance and resistivity are also new for class 10 students, but these are important terms for further classes. Here we learn how to find total resistance when they are attached in parallel or series. The unit of power, consumption of electricity with heating effect and commercial unit of electricity are also important for exams.
Chapter 13: Magnetic Effects of Electric Current
Here we will learn about a compass needle which is a small magnet and its one end, which points towards north, is called a north pole, and the other end, which points towards the south, is called a south pole. Main topics are Magnetic field, the direction of the magnetic field and a metallic wire carrying an electric current has associated with it a magnetic field. Fleming’s Right-hand rule and Left-hand rule for magnetism. We know that an electromagnet consists of a core of soft iron wrapped around with a coil of insulated copper wire. Here we have to study about Magnetic field of a solenoid carrying a current with a comparison of a bar magnet. An electric motor and the phenomenon of electromagnetic induction are also important for exams. Questions are frequently asked on the basis of a generator, live wire, fuse, short-circuiting or overloading.
Chapter 14: Sources of Energy
As we know that our energy requirements increase with our standard of living nowadays. For our energy requirements, we have to improve the efficiency of energy usage and also try and exploit new sources of energy. In Chapter 14 of Class 10 Science, we will learn how we are looking for new sources of energy because the conventional sources of energy like fossil fuels are in danger of getting exhausted soon. Here, we will also learn about some solar devices and their advantages and disadvantages. All the energy sources depend on various factors like the ease and cost of extracting energy from the source. Solar cells, solar cooker, windmills, etc. ultimately derive their energy from the Sun.
Chapter 15: Our Environment
Main topics in Chapter 15 of Class 10 Science are Ecosystem, Food-Chain or Food-Web, Biodegradable or Non-biodegradable, Disposal of waste and CFSs. The various components of an ecosystem are interdependent. We know that the producers make the energy from sunlight available to the rest of the ecosystem. Food web or food chain is based on producers. 10 per cent law describes how the loss of energy take place as we go from one trophic level to the next. The ozone layer is now affected due to excess use of CFCs. The generated waste may be biodegradable or non-biodegradable cause the problem of disposal.
Chapter 16: Management of Natural Resources
In Chapter 16 of Class 10 Science, we will learn how to use our natural resources like forests, wildlife, water, coal and petroleum in a sustainable manner. We should follow RRRRR, means Refuse, Reduce, Reuse, Repurpose and Recycle in our lives. We know that fossil fuels like coal and petroleum will ultimately be exhausted after a few years. In this chapter, we will learn how to utilise the renewable resources which may last for many years.
