>>In short this means, in a real world , air will cool down in expansion ,

Hydrogen and Helium will heat up. In a mix , it is different, effects

and temp will mix.<<



Hmm, let's see.



So I go out into my garage, and blow 1000 psi of He into one of my bottles.



The supply bottle, where the gas is _expanding_, got a little cooler, and the
AL80 I was filling, where the gas is being _compressed_, got warmer.



So in the real world, I guess He cools at it expands, huh?
