Question

Consider two cylinders of gas identical in all respects except that one contains oxygen O_2 and the other helium He. Both cylinders initially contain the same volume of gas at 0degreeC 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. Which gas will show the larger temperature increase? A) the O_2 B) the He C) Neither; both will show the same increase. D) It is impossible to tell from the information given.

Explanation / Answer

Both of the gases obey the same equation: P V = n R T; therefore both will show the same increase.

C) Neither, both will show the same increase
