Chapter 4.7, Problem 5E

(A)

Interpretation Introduction

Interpretation:

The change in entropy.

Concept Introduction:

The formula to calculate the constant volume heat capacity $\left({\widehat{C}}_V\right)$.

${\widehat{C}}_V={\widehat{C}}_P-R$

Here, constant pressure heat capacity is ${\widehat{C}}_P$, and gas constant is $R$.

The expression to calculate the change in entropy $\left(\Delta S\right)$.

$\Delta S=M{\widehat{C}}_V\ln \left(T_1/T_2\right)$

Here, mass of object is $M$, initial temperature is $T_1$, and final temperature is $T_2$.

(B)

Interpretation Introduction

Interpretation:

The change in entropy.

Concept Introduction:

Write the expression to calculate the change in entropy $\left(\Delta S\right)$.

$\Delta S=M{\widehat{C}}_V\ln \left(T_1/T_2\right)$

Here, mass of object is $M$, initial temperature is $T_1$, and final temperature is $T_2$.
