During an adiabatic process, the pressure of a gas is found to be proportional to the cube of its absolute temperature. The ratio `C_P//C_V` for the gas is

A

`3/2`

B

`4/3`

C

2

D

`5/3`

Text Solution

Verified by Experts

The correct Answer is:
A
Since, `P prop T^3`.
For an adiabatic process, `P prop T^(gamma//gamma-1)`
So, `(gamma)/(gamma-1)=3 implies gamma=3/2 implies (C_P)/(C_V)=3/2`
