Question

During melting process, the heat given to a solid is used in
a) Increasing the temperature
b) Increasing the density of material
c) Increasing the average distance between the molecules
d) Increasing the average K.E. of the molecules​

Answer 1

Explanation:

The heat given to the melting solid is used in displacing the molecules from their original position and making their order irregular. It increases the average distance between the molecules.

Answer 2

Explanation:

During melting process, heat given to a body is utilized in increasing the average distance between molecules by decreasing the intermolecular force of attraction.
