Question

Molar heat of sublimation is equal to molar heat of fusion plus

Answer 1

Answer:

Molar heat of vaporization

Explanation:

Just remember what sublimation is, it is the conversion of solid to gaseous state directly. Molar heat of fusion is the energy required to convert solid to liquid(basically the process of fusion) and molar heat of vaporization is the energy required to convert liquid to the gaseous phase. So adding them will give solid to the gaseous phase.
