Chapter 3, Problem 3.36E

Interpretation Introduction

Interpretation:

The expected reliability of answers for $\Delta S$ for parts c, d, and e in exercise 3.34 is to be stated.

Concept introduction:

The term entropy is used to represent the randomness in a system. When a system moves from an ordered arrangement to a less ordered arrangement, then the entropy of the system increases. The change in entropy is given as follows.

$\Delta S={\displaystyle \int \frac{d{q}_{\text{rev}}}{T}}$

Where,

• $q_{\text{rev}}$ represents the heat exchange.

• $T$ represents the temperature.
