Question

Why is the heat of fusion of a substance smaller than its heat of vaporization?

Answer 1

Answer:

The heat of fusion is smaller than the heat of vaporization because melting requires only enough energy for molecules to escape from their sites in the crystal lattice, leaving other molecular attractions intact.

Answer 2

Answer:

" The heat of fusion is smaller than the heat of vaporization because melting requires only enough energy for molecules to escape from their sites in the crystal lattice, leaving other molecular attractions intact.so

Explanation:

this can be heat of fusion for heat vapourization
