Sophie Maldonado · Answer 1

Under 2, greater than

Explanation:

With both containers having the same size, gas pressure, temperature, the velocity of the gass will be determined basically by the characteristics of the gas. With the O2 molecules being much bigger than the H2 molecules, it would result in more hits between the molecules and the walls of the containers, resulting in a bigger average velocity for the O2 molecules.

So the answer is under 2, greater than.
