Which term is used to describe the amount of heat that is required to melt 1 mol of a substance?

Melting changes a substance from a solid to a liquid. The heat required for this change is called the heat of fusion; when it is stated for 1 mol, it is the molar heat of fusion, so the correct choice is “heat of fusion.” Specific heat describes temperature change, while heat of vaporization applies to boiling.
