Chapter 18, Problem 8QP

Interpretation Introduction

Interpretation:

The entropy changes for the given processes are to be determined.

Concept introduction:

The entropy of a system is the distribution of energy in the space and it is related to the randomness of the molecules.

For the phase-change equilibrium, the trend of the entropy is given as:

$S_{(gas)}>S_{(liquid)}>S_{(solid)}$

Here, $S$ is the entropy.
