An ideal monoatomic gas is taken around the cycle ABCDA, wher co-ordinates of A, B, C and D on and D on `P-V` diagram are A`(p,V), B(2p,V), C(2p, 2V) and D(p, 2V)`. Calculate work done during the cycle.

Answer

`pV`

Explanation

The `P-V` diagram of the cyclic change is shown in (figure). Work done during the cycle.
`= area of squar e ABCDA`
`= ABxxBC= (2p-p)(2V-V)= pV`
