Two cylinders of gas are identical in every way, except one contains oxygen gas, the other contains helium gas. Both hold the same volume of gas at STP and are closed by a movable piston at one end. Both gases are now compressed adiabatically to one-third their original volume. Which gas will show the greater temperature increase, or will they both show the same temperature increase? Thanks.
