NCERT Solutions for Class 10 Science: Questions and Answers

Physics Questions and Answers

What is the difference between speed and velocity? Speed is a scalar quantity that represents the distance traveled per unit of time, whereas velocity is a vector quantity that describes the speed of an object in a specific direction.

What is the law of reflection? The law of reflection states that the angle of incidence is equal to the angle of reflection when a light ray strikes a reflecting surface.

What do you mean by the term 'acceleration'? Acceleration is the rate at which an object changes its velocity. It can be positive (increasing speed) or negative (decreasing speed).

Explain the working of a simple electric motor. A simple electric motor works based on the principle of electromagnetism. When a current-carrying conductor is placed in a magnetic field, it experiences a force, which causes the motor's armature to rotate.

What is the relationship between force and momentum? The force applied on an object is related to the rate of change of momentum. According to Newton’s second law, force equals the change in momentum per unit time.

What is the principle of conservation of energy? The principle of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another.

What are the different types of energy? There are several forms of energy, including kinetic energy, potential energy, thermal energy, chemical energy, electrical energy, and light energy.

How does the reflection of light occur in a concave mirror? When parallel rays of light strike a concave mirror, they converge at a point called the focal point after reflection.

What is the work-energy theorem? The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy.

What are the laws of motion formulated by Newton? Newton's three laws of motion describe the relationship between a body and the forces acting on it, and its motion in response to those forces.

Chemistry Questions and Answers

What is an atom? An atom is the smallest unit of matter that retains the properties of an element. It consists of protons, neutrons, and electrons.

What is the difference between ionic and covalent bonds? Ionic bonds occur when electrons are transferred from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

What is the significance of the periodic table? The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties, providing a useful framework for studying chemistry.

What is a chemical reaction? A chemical reaction is a process where substances (reactants) are transformed into new substances (products) with different chemical properties.

What is the role of a catalyst in a chemical reaction? A catalyst speeds up a chemical reaction by lowering the activation energy required, without being consumed in the reaction.

What is a neutralization reaction? A neutralization reaction occurs when an acid reacts with a base to form water and salt.

How does the process of rusting occur? Rusting is an oxidation reaction where iron reacts with oxygen and moisture in the environment to form iron oxide (rust).

What are the different types of chemical bonds? There are three main types of chemical bonds: ionic, covalent, and metallic bonds.

What is the law of conservation of mass in a chemical reaction? The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

What is an exothermic reaction? An exothermic reaction is a chemical reaction that releases energy, usually in the form of heat, to the surroundings.

Biology Questions and Answers

What is photosynthesis? Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water, producing oxygen as a byproduct.

What is the function of the human respiratory system? The human respiratory system is responsible for the intake of oxygen and the removal of carbon dioxide, enabling cellular respiration.

What are the three types of muscles in the human body? The three types of muscles are skeletal muscles (voluntary), smooth muscles (involuntary), and cardiac muscles (found in the heart).

What is the process of digestion in humans? Digestion is the breakdown of food into simpler substances, occurring in the mouth, stomach, and small intestine, with the help of enzymes and other digestive fluids.

What is the role of white blood cells in the immune system? White blood cells play a crucial role in the immune system by identifying and attacking harmful pathogens, like bacteria and viruses.

What is the difference between mitosis and meiosis? Mitosis is the process of cell division that results in two identical daughter cells, while meiosis produces four genetically distinct daughter cells, crucial for sexual reproduction.

What is the importance of vitamins in the body? Vitamins are essential nutrients that support various body functions, including immune system regulation, energy production, and maintaining healthy skin and bones.

What are the main components of blood? The main components of blood are red blood cells, white blood cells, platelets, and plasma.

What is the function of the kidneys in the human body? The kidneys filter waste products from the blood, regulate water balance, and help maintain electrolyte levels.

What is the structure of a plant cell? A plant cell has a rigid cell wall, a central vacuole, chloroplasts for photosynthesis, and other organelles like the nucleus and mitochondria.
