Chapter 19, Problem 34E

Interpretation Introduction

Interpretation:

The values of entropy change for the vaporization of water at $25°\text{C}$ and $25°\text{C}$ are to be determined; also the reason for the difference in values is to be determined.

Concept Introduction: The entropy change of vaporization of water is calculated by the formula,

$\Delta S=\frac{\Delta H_{\text{vap}}}{T}$
