Chapter 4, Problem 4F.5AST

Interpretation Introduction

Interpretation:

The change in the entropy of the argon gas has to be determined.

Concept Introduction:

The degree of randomness in a system is the measured in terms of entropy.  Higher the entropy greater will be the disorder in the system.  The mathematical expression for the calculation of entropy for an isothermal expansion in terms of initial and final volume is shown below.

$\Delta \text{S}=\text{nR}\text{ln}\left(\frac{{\text{V}}_2}{{\text{V}}_1}\right)$

The mathematical expression for the calculation of entropy in terms of initial and final temperature at constant final volume is shown below.

$\Delta \text{S}=\text{C}\text{ln}\left(\frac{{\text{T}}_2}{{\text{T}}_1}\right)$
