A thermodynamics system is taken trough ...

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

A

a. `(1)/(2)PV`

B

b. `PV`

C

c. `2PV`

D

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
