Consider two cylinders of gas identical in all respects except
that one contains O 2 and the other He. 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 pressure increase?
a. He
b. O2
c. neither; both will show the same increase
d.it is impossible to tell from the information given
