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

2

B

1.5

C

`(5)/(3)`

D

`(4)/(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
`PpropT^3`
`(gamma)/(gamma-1)=3` (see solution of previous problem)
`gamma=3gamma-3impliesgamma=(3)/(2)=1.5`
