Answer

Answer:

C. The energy needed to completely vaporize a mole of a liquid

Brief Explanations:

Latent heat of vaporization specifically refers to the energy required to convert a substance from its liquid phase to vapor phase at a constant temperature (its boiling point), without a change in temperature. Option A describes sensible heat for heating a liquid through a temperature range, option B refers to latent heat of fusion, and option D describes specific heat capacity of a vapor.
