Complete Learning Breakdown of NCERT Solutions Class 10 Science
The NCERT Solutions for Class 10 Science provide a complete guide to understanding all important concepts in a clear and structured way.
From chemical substances and their reactions to carbon compounds and electricity, each topic is explained simply for easy learning.
These solutions help students strengthen their fundamentals, practice numerical problems, and gain confidence in answering questions effectively.
Chapter 1 Chemical Reactions and Equations
This chapter introduces chemical changes where reactants form products through bond breaking and forming. Students learn to write and balance equations per the law of conservation of mass, covering types like combination, decomposition, displacement, double displacement, and redox reactions. Real-life examples include corrosion (rusting) and rancidity in food.
Chapter 2 Acids, Bases, and Salts
Acids release H+ ions and taste sour, while bases release OH- ions and feel slippery; pH scale measures their strength from 0-14. The chapter explains neutralization reactions forming salts and water, with uses like antacids and Plaster of Paris. Indicators like litmus and phenolphthalein help identify them in daily life.
Chapter 3 Metals and Non-metals
Metals conduct electricity, are malleable, and form basic oxides, unlike non-metals which are brittle and form acidic oxides. Key topics include reactivity series for displacement reactions, corrosion prevention via galvanization, and extraction of metals from ores. Ionic compounds form via electron transfer between them.
Chapter 4 Carbon and its Compounds
Carbon's tetravalency enables catenation, forming vast compounds like hydrocarbons (alkanes, alkenes, alkynes). Versatile nature covers covalent bonding, ethanol (alcohol), ethanoic acid (vinegar), soaps, and detergents via saponification. Functional groups and combustion reactions highlight its role in fuels.
Chapter 5 Life Processes
Living organisms maintain life via nutrition (autotrophic like photosynthesis, heterotrophic), respiration (aerobic/anaerobic), transportation (xylem/phloem in plants, blood in humans), and excretion (kidneys/nephrons). These processes ensure energy flow and waste removal for survival.
Chapter 6 Control and Coordination
The nervous system (neurons, reflex arcs) and hormonal system (endocrine glands like thyroid, adrenal) coordinate responses. Plants use tropisms (phototropism) and hormones like auxin. Human brain parts like cerebrum handle voluntary actions.
Chapter 7 How do Organisms Reproduce?
Asexual modes include fission, budding, fragmentation; sexual involves gametes, fertilization, and development. Human reproductive system covers menstrual cycle, contraception methods, and STDs. Reproduction ensures species continuity.
Chapter 8 Heredity and Evolution
Mendel's laws explain inheritance via genes/alleles; sex determination occurs via XY chromosomes. Evolution via natural selection, speciation, and human evolution traces (Homo sapiens) show common ancestry. Acquired vs. inherited traits clarified.
Chapter 9 Light – Reflection and Refraction
Laws of reflection (angle i = r); spherical mirrors form images via ray diagrams (concave real/virtual). Refraction follows Snell's law (n = sin i / sin r); lenses (convex/concave) power in dioptres for magnification.
Chapter 10 Human Eye and the Colourful World
Eye structure (cornea, retina) accommodates via lens; defects like myopia/hyperopia corrected by lenses. Atmospheric refraction causes twinkling stars, delayed sunrise; scattering explains blue sky and red sunsets.
Chapter 11 Electricity
Electric current (I = V/R via Ohm's law); series/parallel circuits affect resistance. Heating effect (Joule's law H = I²Rt); power P = VI. Factors like resistivity and safety devices like fuses covered.
Chapter 12 Magnetic Effects of Electric Current
Magnetic field lines around current-carrying conductors; Fleming's rules for motor/generator. Solenoid acts like bar magnet; electric motor converts electrical to mechanical energy. Earth's magnetism aligns compass.
Chapter 13 Our Environment
Ecosystem components (producers, consumers, decomposers); energy flow is unidirectional via food chains (10% rule). Human activities cause pollution; biodegradable/non-biodegradable waste management promotes sustainability.
