Question
Why does hydrogen gas escape faster than oxygen from the earth’s atmosphere?
Solution
Root mean square velocity of gas molecule is given by,
i.e.

∴
That is, escape velocity of hydrogen is 4 times that of the escape velocity of oxygen gas.
Hence, hydrogen gas has more tendency to escape than oxygen from the Earth's atmosphere.
