If the ratio of specific heat of a gas of constant pressure to that at constant volume is `gamma`, the change in internal energy of the mass of gas, when the volume changes from `V` to `2V` at constant pressure `p` is

A

PV

B

3PV

C

`(PV)/(gamma-1)`

D

`(RV)/(gamma-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
`dU = muC_(V)dt=(muRdT)/(gamma-1)=(P(2V-V))/(gamma-1)=(PV)/(gamma-1)`
