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)/(gamma-1)`

B

`PV`

C

`gamma-1`

D

`(PV)/(gamma)`

Text Solution

Verified by Experts

The correct Answer is:
A
`DeltaU=nC_(V)DeltaT`
But `C_(V)=(R)/(gamma-1)` and PdV=RdT
