The volume of an ideal gas (γ = 1.5) is changed adiabatically from 4.00 litres to 3.00 litres. Find the ratio of

(a) the final pressure to the initial pressure and

(b) the final temperature to the initial temperature.

Here γ= 1.5, V1=4, V2=3.Let P1 and P2 be the initial and final pressure

(a)Since it is an adiabatic process, So PVγ = const.


(b)Also for an adiabatic process, TVγ -1=constant
