Some hydrogen gas is enclosed within a chamber being held at 200 degrees C with a volume of 0.025 m^3. The chamber is fitted with a movable piston. Initially, the pressure in the gas is 1.5*10^6 Pa (14.8 atm). The piston is slowly extracted until the pressure in the gas falls to .95*10^6 Pa. What is the final volume of the container? Assume that no gas escapes and that the temperature remains at 200 degrees C.
