Consider two cylinders of gas identical in all respects except that one contains oxygen o2 and the other helium he. both cylinders initially contain the same volume of gas at 0â°c and 1 atm of pressure and are closed by a movable piston at one end. both gases are now compressed adiabatically to one-third their original volume. (a) which gas will show the greater temperature increase?
