Question

with reference to inter conversion of matter on the basis of kinetic theory explain in brief the convension of a solid into a liquid

Answer 1

On heating a solid substance, the kinetic energy of its constituent particles increases. As a result, the particles start vibrating with greater speed. This extra energy helps the particles to overcome the inter-particle force of attraction and then solid substance change into liquid. The change of solid state into liquid state is known as fusion.

Answer 2

Answer:

a. A Solid into a Liquid

Ans: On heating solids, temperature rises, the particles gain energy as the heat energy

supplied to the solid is absorbed by its molecules and stored as potential energy.

The stored potential energy increases the inter-particle space and consequently

the inter-particle force of attraction decreases. At melting point, the solid particles

become free and the solid changes into a liquid.
