(a) Compute the increase in gravitational potential energy for a nitrogen molecule (molar mass 28.0 g/mol) for an increase in elevation of 400 m near the earth's surface.
(b) At what temperature is this equal to the average kinetic energy of a nitrogen molecule?
(c) Is it possible that a nitrogen molecule near sea level where T = 15.0oC could rise to an altitude of 400 m? Is it likely that it could do so without hitting any other molecules along the way? Explain.
