Chapter 17, Problem 49E

Interpretation Introduction

Interpretation:

The sign of ${\text{ΔS}}_{\text{sys}}$ for the given process is to be predicted.

Concept introduction: ${\text{ΔS}}_{\text{sys}}$ is change in entropy of a system. The sign of $\Delta S_{\text{sys}}$ depends on the randomness or disorderness in the system. If randomness of a system increases, then the sign of ${\text{ΔS}}_{\text{sys}}$ will be positive. If randomness of a system decreases, then the sign of ${\text{ΔS}}_{\text{sys}}$ will be negative.
