An ideal gas is taken around ABCA as shown in the $\mathrm{P}-\mathrm{V}$ diagram. The work done during a cycle is
2PV
PV
$\frac{1}{2}PV$
Zero
Solution
The work done during the cycle ABCA is $\mathrm{W}=$ Area of triangle $A B C$ on $P-V$ plane
$=\frac{1}{2} \times(3 \mathrm{~V}-\mathrm{V}) \times(3 \mathrm{P}-\mathrm{P})=2 \mathrm{pV}$
