Question 63: Thermodynamics & KTG

Question

A gas is taken through the cycle $A \rightarrow B \rightarrow C \rightarrow A$, as shown in figure. What is the net work done by the gas?

Accepted Answer

Net work done by the gas = Area enclosed in $p$-$V$ curve, i.e. area of $	riangle A B C$.
$W_{	ext {net }}=\frac{1}{2} 	imes 5 	imes 10^{-3} 	imes 4 	imes 10^5 \mathrm{~J}=10^3 \mathrm{~J}=1000 \mathrm{~J}$
