Charles and Boyles gas laws say that the composition of the gas doesn't 
matter.....provided it's pure gas....throw a little water vapor in and the 
bets are off.

One of the reasons nitrogen is used in aviation is that it comes from a 
bottle so is DRY.

Of course it's more expensive than compressed air which is another reason to 
use it the military and aviation bidness!!
