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

`2/3`

C

`4/3`

D

`5/3`

Text Solution

Verified by Experts

The correct Answer is:
A
In an adiabatic process,
`P propT^(gamma/(gamma-1)) propT^(3)` (given)
`:. (gamma)/(gamma-1)=3`
`3gamma-3=gamma`
`2gamma=3, gamma=3/2`
