Under an adiabatic process, the volume of an ideal gas gets doubled. Consequently the mean collision time between the gas molecule changes from `tau_(1)` to `tau_(2)` . If `(C_(p))/(C_(v))=gamma` for this gas then a good estimate for `(tau_(2))/(tau_(1))` is given by :

A

2

B

`((1)/(2))^((tau+1)/(2))`

C

`(1)/(2)`

D

`((1)/(2))^(gamma)`
