During an adiabatic process, the pressure of a gas is found to be proportional to cube of its absolute temperature. The poision's ratio of gas is:

Options

A. `(3)/(2)`
B. `(5)/(3)`
C. `(7)/(2)`
D. `(4)/(3)`

Answer

1

Explanation

`(gamma)/(T^(1-gamma)),P=` constant `PpropT(gamma)/(gamma-1)`
`:'" "PpropT^(3)`
`:." "(gamma)/(gamma-1)=3," "gamma=(3)/(2)`
