A cylindrical vessel of unifrom cross-section consisting of a gas of gamma =1.5 is divided into two parts A and B using a piston. Intially the piston is kept fixed such that part A has pressure p and volume 5 v and the part B has pressure 8 p and volume V. If the piston is let free and the gas is allowed to undergo adiabatic process, then the final volume of the gas in part A is
