Chapter 5, Problem 105AP

Interpretation Introduction

Interpretation:

Thework done and change in internal energy is to be calculated.

Concept introduction:

The amount of work done by a pressure–volume work process is calculated as

$w=-P\Delta V$

Here, $P$ represents the applied pressure, $w$ is work done, and $\Delta V$ is the volume change for the material.

The change in internal energy of the system is calculated as

$\Delta \text{U}=q+w$

Here q is the heat, $\Delta \text{U}$ is change in internal energy, and w is the work done.
