The atmosphere of the Earth is an infinite volume, and in fact it demonstrates
rather well that the combined laws don't apply in that case. *Pressure is
largely uncorrelated with temperature, for example.

Go back to the post you originally made the riduculous comment on and
tell us why

D =PM/ RT does not apply in the Earths atmosphere for any given local
measurement of pressure and temperature.
