pv=nrt

[asaratis]

The Patriot football saga can be reduced to an understanding of physics regarding confined gases:

pv=nrt

ideal gas law
n.
A physical law describing the relationship of the measurable properties of an ideal gas, where P (pressure) × V (volume) = n (number of moles) × R (the gas constant) × T (temperature in Kelvin). It is derived from a combination of the gas laws of Boyle, Charles, and Avogadro. Also called universal gas law.

For a container (the football in this case) with no leaks, "n" and "r" do not change. When the temperature changes, the product of "p" (pressure) and "v"(volume) must go down.

This does not prove that the balls were legal, just that the pressure could have been decreased without releasing any of the air inside.

My understanding is that the balls are used for one half of the game only...and that the balls used in the first half of the game were found to be properly inflated. The Patriots scored 28 points in the first half.

All that is real interesting except that one pesky football that was at regulation pressure shoots all your fancy math out of the ballpark.

Nay, nay! Perhaps 11 balls were submitted with pressures at the low end of the limit (12.5 psi) and 1 ball was submitted at the high end of the limit (13.5 psi)..the higher pressure ball being intended for use in punting only. The pressure in that ball could have remained within limits.
