For water $\triangle_{vap} S^{∘}$ = + 109 J K^-1 mol^-1 whilst $\triangle_{fus} S^{∘}$ = + 22 J K^-1 mol^-1. The entropy change for vaporization is larger than the entropy change for fusion because it is measured at a higher temperature.

Question

Quizplus · Accepted Answer

The entropy change for vaporization is larger because the transition from liquid to gas involves a greater increase in disorder compared to the transition from solid to liquid, not because of the temperature at which it is measured.
