Heats of vaporization are greater than heats of fusion.

Question

Quizplus · Accepted Answer

Heats of vaporization are the amount of energy required to turn a substance from a liquid to a gas, while heats of fusion are the amount of energy required to turn a substance from a solid to a liquid. The intermolecular forces between molecules are stronger in the liquid state than the solid state, so more energy is required to break these forces and turn the substance into a gas. Therefore, heats of vaporization are greater than heats of fusion.
