A cylindrical tank has a tight-fitting piston that allows the volume of the tank to change. The tank contains 0.5m^3 of air at a pressure of 2*10^5 Pa. The piston is slowly pushed in until the pressure of the air is increased to 2.5*10^5 Pa. If the temperature remains constant, what is the final value of the volume?
