Elaborate the reason that the heat of vaporization of water is so much greater than its heat of fusion.
a) the potential energy of fusion represents a greater change of stored energy.
b) liquid water is stabilized by strong intermolecular forces between the molecules.
c) the kinetic energy of the water molecules is so much greater in the liquid state.
d) the bonding forces for solid water are much stronger than the bonding in the liquid.

B) Liquid water is stabilized by strong inter molecular forces between the molecules.

Explanation: Latent heat of fusion is the amount of heat required to convert 1 gram of solid into its liquid state without change in its temperature. The latent heat of fusion of water is 6.01 kJ/mol.

Latent heat of vaporization is the amount of heat required to convert 1 gram of liquid into its vapor state without change in its temperature. The latent heat of vaporization of water is 40.67 kJ/mol.

In fusion or melting,  the molecules just need enough energy to slide around each other, while for vaporization, the molecules  need enough energy to completely escape and turn into vapor form. Thus the enthalpy of vaporization is always higher than the enthalpy of fusion.
