Chapter 2, Problem 2.17NP

Interpretation Introduction

Interpretation: The temperature of the system after the establishment of the thermal equilibrium needs to be determined.

Concept Introduction: The change in internal energy is calculated as follows:

  $\Delta U=n{C}_{V.m}\left(T_f-T_i\right)=q+w$

Here, n is number of moles, $C_{V,m}$ is molar heat at constant volume and T is temperature.

Also, q is heat transferred and w is work done.

The work done is represented as follows:

  $w=-P_{\text{external}}\Delta V$

Here, P is external pressure and $\Delta V$ is change in volume.
