An ideal gas undergoes cyclic process ACBC as shown is given PV diagram

The amount of work done by the gas is

A

`6Po Vo`

B

`-2Po Vo`

C

`+2Po Vo`

D

`+4 Po Vo`

Text Solution

Verified by Experts

The correct Answer is:
B
Work done by the gas is equal to area of rectangle ABCDA fig.
`=AB xxBC`
`=(2Vo)Po = 2 PoVo`
As the trace is anticlockwise, the work is done on the gas. Work done by the gas = –2PoVo
