One positive thing coming out of #Deflategate is that people are finally seeing the Ideal Gas Law applied to something that is getting a lot of attention. PV=nRT Using a online calculator, assuming 70F for testing inside, 12.5 psi starting, volume of football at 4237 cm3, calculating the moles at 0.158 I get that dropping the balls temperature to 41F would cause the ball pressure to drop by 0.7 psi. Ok, you can go back to thinking whatever you want about who did or did not deflate the New England Patriots balls, but hopefully having learned a little something about science.
