A thermodynamic system is taken through ...

A thermodynamic system is taken through the cycle ABCD as shown in figure. Heat rejected by the gas during the cycle is

A

2PV

B

4PV

C

`(1)/(2) PV`

D

PV

Text Solution

Verified by Experts

The correct Answer is:
A
In cyclic process `DeltaU=0`
So heat absorbed
`DeltaQ=W` =Area under the curve
`=-(2V)(P)=-2PV`
So heat rejected =2PV
