Explanation:

Energy is transferred to a substance to melt or boil it. This energy is needed to overcome the bonds or forces of attraction between the particles in the substance: some forces of attraction are overcome during melting, allowing molecules to move over each other.

Answer 2

Every substance also has an associated vapor pressure with it. The vapor pressure is defined to be the amount of gas of a compound that is in equilibrium with the liquid or solid. If the intermolecular forces are weak, then molecules can break out of the solid or liquid more easily into the gas phase.
