Question

State any two effects of heat on matter?

Answer 1

Answer:When heat is added to a solid, the particles gain energy and vibrate more vigorously about their fixed positions, forcing each other further apart. As a result expansion takes place. Similarly, the particles in a liquid or gas gain energy and are forced further apart. The degree of expansion depends on the substance.

Answer 2

Answer:

Two effects of heat on matter are —

1. Liquid expands when it is heated so the volume of liquid increases due to increase in heat.

2. When the gas is heated, the molecules become more energetic, move faster and are further apart.
