I have my chem eng degree and pro license and experience in various industries working on the situation. So far it appears that there is much to do about what and how natural conditions and causes could affect a manufactured object that is about to be tossed about and kicked about. It would be very difficult to strictly apply the ideal/perfect gas law(s) to a football. A person might throw in some of the fudge factors developed over years of research but it seems to me that trying to make a court like case for use of an inflatable ball that has been subjected to specified reasonable conditions is a bit too much.
“It would be very difficult to strictly apply the ideal/perfect gas law(s) to a football.”
That was my my position as well, that ideal gas law wasn’t applicable because we were not dealing with an ideal gas.That’s what I was trying to tell Smokin’ Joe.
Dalton’s law of partial pressures could play apart, if we knew what gas(s) were actually in the football. Topping them off with CO2 for instance, could very well make them loose 2 pounds of pressure at 45 degrees. And it could have been done quite innocently.
