Chapter 4, Problem 4F.9E

Interpretation Introduction

Interpretation:

The change in entropy has to be calculated.

Concept Introduction:

The change in entropy of the gas is calculated using the formula,

  $\text{ΔS=nR}\text{ln}\left(\frac{{\text{P}}_{\text{1}}}{{\text{P}}_{\text{2}}}\right)$

Here $\text{ΔS}$ is the change in the entropy

    n is the number of moles

    R is the gas constant

  ${\text{P}}_{\text{1}}$ is the initial pressure

  ${\text{P}}_{\text{2}}$ is the final pressure
