Consider two equal-sized containers, one filled with h2 gas and one with o2 gas at the same temperature and? and pressure. the average velocity of the o2 molecules is (equal to, greaterthan, less than) that of the h2 molecules.1. greater than2. equal to3. less than

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.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
