Q. An ideal monoatomic gas is taken around the cycle ABCD as shown in the p-V diagram. The work done during the cycle is given by
A) $\frac{1}{2}pV$
B) $pV$
C) 2$pV$
D) 4$pV$
Explanation
(b) Work done during the cycle
=area enclosed by p-V graph
=area of ▭ ABCD
$= AD \times CD$
$= (2V - V) \times (2p - p) = pV$
