So have they PROVED the Patriots did it? Even though the officials hold the ball after every play?What you think should be the penalties issued to the patriots after the NFL found that 11 out of 12 ball balls were deflated allegedly by the patriots?
PV = nRT. Reducing the temperature (T) does reduce pressure (P) in a given volume (V). R is a constant. The weight of the ball comes from the container (i.e., the pigskin) and the amount of air which is related to n, the number of moles (if you don't want to revisit chemistry just think of it as the number of air molecules). If the temperature changes up or down, as long as no air leaks out and no air is added in, the weight should not change.Anyone else think that cold temps reduced the air presure in the balls? The same thing happens to my tire pressure every winter.
Aaron Rodgers calls out refs as culprits for deflating footballs regularly.

What about the Ravens game?They would have never lost the game but the guy always needs the "edge". He's a cheat a** and should be reprimanded for a year!

You're giving me flash backs to Thermodynamics I
The media doesn't like to tell the whole story. Once the ref's checked out the balls at halftime and made adjustments the Pats out scored the Colts 28-0. So the deflated balls actually hurt the Pats.
That's why I talked about air pressure and not weight. Remember Gay-Lussac's Law? (Snicker I said Gay-Loose sack.)PV = nRT.

We have to see if they also weighed the balls, and also if they allowed the footballs to warm up to controlled temperature before measuring the pressure. Those details weren't in Mortenson's reporting. If they did either one of those the case is pretty airtight (pun intended).That's why I talked about air pressure and not weight.

P1/T1 = P2/T2. So the answer to the somewhat rhetorical question is temperature does effect volume.
The NFL's preliminary findings were that 11 of 12 balls were under-inflated by 2 pounds per square inch of air. That's a measurement of air pressure, not weight.
Pats fan here. If the NFL decides to suspend belichek for all of next year, he will have earned it.
