Problem

A gas undergoes the following two-step process: 1. Expansion from

V=0.015\,\text{m}^3

0.030\,\text{m}^3

while the pressure decreases linearly from

400\,\text{kPa}

100\,\text{kPa}

. 2. Compression at a constant pressure of

100\,\text{kPa}

back to the original volume of

0.015\,\text{m}^3

. Determine the numerical value (with sign) of the net work done ON the gas for the entire process.
