A thermodynamics system is taken trough the cycle ABCD as shown in figure. Heat rejected by the gas during the cycle is:

A

`(1)/(2)PV`

B

`PV`

C

`2PV`

D

`4PV`

Text Solution

Verified by Experts

The correct Answer is:
C
For given cyclic process, `DeltaU=0`
`therefore Q= W` (From first law of thermodynamic `Q=DeltaU+W)`
Also W= - are enclosed by the curve `=-P xx2V`
`therefore` Heat rejected =2PV
