thermodynamics

a heat conducting piston can freely move inside a closed thermally insulated cylinder with an ideal gas. in equilibrium the piston divides the cylinder into 2 equal parts , the gat Temp. being equal to T0 . the piston is slowly displaced . find the gas temp as a funcn of the ratio n of the volumes of the greater and smaller sections . the adiabatic exponent of the gas is equal to y..
