Chapter 17, Problem 17.51QE

(a)

Interpretation Introduction

Interpretation:

The entropy change for the process of $\text{1}\text{.0 mol}{\text{H}}_{\text{2}}\text{O}\left(\text{s}\right)$ melts at ${\text{0}}^{\text{o}}\text{C}$ has to be calculated.

(b)

Interpretation Introduction

Interpretation:

The entropy change for the process of $\text{2}\text{.0 mol}{\text{C}}_{\text{6}}{\text{H}}_{\text{6}}\left(l\right)$ vaporizes at ${\text{80}}^{\text{o}}\text{C}$ has to be calculated.
