Chapter 16, Problem 16.106CHP

Interpretation Introduction

Interpretation:

The entropy change when $1.32\text{ g}$ of propane at $0.100\text{ atm}$ pressure is compressed by a factor of five at constant temperature of $20°C$ has to be calculated.  The gas has to be assumed as ideal gas.

Concept Introduction:

Entropy change in a process involving compression or expansion of gases at constant temperature is calculated using the formula,

$\Delta S=nR\ln \left(\frac{V_f}{V_i}\right)$

Where,

$\begin{array}{l}R=\text{ Universal gas constant}\\ {\text{V}}_f=\text{ final volume}\\ {\text{V}}_i=\text{ initial volume}\\ \text{n}\text{= number of moles of gas}\end{array}$
