Question

entropy of vaporization

Answer 1

The entropy of vaporization is the increase inentropy upon vaporization of a liquid. This is always positive, since the degree of disorder increases in the transition from a liquid in a relatively small volume to a vapor or gas occupying a much larger space.

Answer 2

The entropy of vaporization is the increase in entropy upon vaporization of a liquid. ... The entropy of vaporization is then equal to the heat of vaporization divided by the boiling point. According to Trouton's rule, the entropy of vaporization (at standard pressure) of most liquids is about 85 to 88 J mol−1 K−1.
