Chapter 1: Science (Class 8)
1. Define Matter and its different states.
Matter is anything that occupies space and has mass. It exists in three states - solid, liquid, and gas. Solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, and gases have neither a definite shape nor volume.
2. Explain the difference between Physical and Chemical Changes.
Physical changes do not alter the chemical composition of a substance, only its physical properties. Examples include melting, freezing, and boiling. Chemical changes result in the formation of new substances with different properties. Examples include burning, rusting, and digestion.
3. Describe the Law of Conservation of Mass.
The Law of Conservation of Mass states that during a chemical reaction, matter is neither created nor destroyed. The total mass of the reactants is equal to the total mass of the products.
Chapter 2: Science (Class 8)
1. Define Force and its types.
Force is a push or pull that can change the state of motion of an object. There are four types of forces - gravitational, electromagnetic, weak nuclear, and strong nuclear.
2. Explain the difference between Balanced and Unbalanced Forces.
Balanced forces are equal in magnitude and opposite in direction, resulting in no change in an object's motion. Unbalanced forces are unequal in magnitude, causing a change in an object's motion.
3. Discuss the concept of Friction.
Friction is the force that opposes the motion of objects in contact with each other. It can be helpful (e.g., walking) or harmful (e.g., wear and tear on machinery).
