Google Classroom

You might need: Calculator

A gas is taken through the cycle shown below.

The values of the pressure and volume at the various points is given in the table below.

Quantity	Value
$P_{1}$ ‍	$2 \times 10^{5} N / m^{2}$ ‍
$P_{2}$ ‍	$10^{5} N / m^{2}$ ‍
$V_{A}$ ‍	$1 m^{3}$ ‍
$V_{B}$ ‍	$8 m^{3}$ ‍
$V_{C}$ ‍	$6 m^{3}$ ‍
$V_{D}$ ‍	$2 m^{3}$ ‍

What is the net work done by the gas in the complete cycle?

\times 10^{5} J
