Well, I'll let the expert chime in later, but as I recall Boyle's Gas
Law (Hope it was Boyle anyway) says pressure and temp and volume are
related. I don't think the make up of the gas has any thing to do with
volume (unless it is related to Avragado's number, which is).
Like I said, Leave to the experts, but I do not think that use of 100%
N2 over common air is in anyway related to temp. Gotta be another
reason they use it.
