Therefore at 0degC, hydrogen molecules have the velocity of,
1.84 x 10^3 m s-1
at 0degC oxygen molecules have the average speed of,

An important note to this to keep in perspective the idea of the
velocities and collisions and supposed transfer of kinetic energy, the
mean free path or distance a molecule moves between collisions @stp
is only 500 Angstroms, or 200 times it's own diameter


So 1 mole of gas surrounding a steel ball with surface area of 1 sq
meter will encompass 2.08 cm of radius in it's volume around the ball.

Actually at 300K, the volume of the gas is 300/273 = 1.0989 x 22,400
=
24,615cc
92,024+ 24,615 =
30.31 cm radius of 1 mole of air around sphere of 1sq meter surface
area.
30.31 - 28.209 =
2.1 centimeter of added radius for the volume of 1 mole of gas around
the sphere of 1 sq meter surface area @300degK, or 81F.
