An ideal mono-atomic gas follows the path `ABCD`. The work donw during the complete cycle is

A

`-PV`

B

`-2PV`

C

`-(1)/(2)PV`

D

Zero

Text Solution

Verified by Experts

Net wrok done during the complete cycle is equal to area under the cycle (-ve if the cycle is clockwise, i.e. work done by the gas and +ve when cycle is anticlockwise, i.e. work done on the gas)
`w =- P xxV =- (2P - P) xx(2V - V) =- PV`
