An ideal gas with pressure P, volume V and temperature T is expanded isothermally to a volume 2V and a final pressure `P_i`, If the same gas is expanded adiabatically to a volume 2V and a final pressure `P_alpha` find the value of ratio `P_alpha/P_i`. The ratio of the specific heats for the gas is 1.67.
