Why?

It's what gases do. The particles are constantly bouncing away from
each other. This is pretty simple physics - something that should
almost be intuitive. If you have a cylinder of gas with an
air-tight piston and pull back on the piston and double the size of
the volume do you seriously think the gas will not expand into the
other half as fast as it can to try and stay in contact with the
piston?

If you are having this much trouble on a basic concept of gases,
then I see no value in you or anyone else investing time in dealing
with your questions, which you chose to post to an inappropriate
newsgroup anyway.

Grumble. Now I recall why I had established a personal policy to
stay away from discussions of aerodynamics on this newsgroup:
futility avoidance.

I applaud. Very well put.

Not well put.

What Jim is describing here and what I was refuting are two different
things.

Yeh, he's telling you how it works and you're describing th einside of
your Skull, which apparently has just been set up for staging a tour of
"Fjukkwits on ice"
