Use what you know about compressible fluids to dispute or confirm this statement. Tom Brady was innocent. Of course those footballs had a lower pressure - they were outside where it was colder. No foul play - just thermodynamics!\" Note - A football should be pressurized at 12.5 to 13.5 psi. Eleven of twelve footballs measured at halftime were \"2 psi below the minimum\". What assumptions have you made? If you were given 12 footballs and an accurate pressure gauge, how could you avoid any of the assumptions necessary for the analytic conclusion?

Solution

The statement written is perfectly correct for incompressible fluids but for compressible fluid there may be some variation, but the result will be the same. Let\'s take the ideal gas equation:

pv=nRT

p: Pressure, v: Volume, R: Universal Gas Constant, T: Absolute Temperature

Assumption: Volume of football remains constant as it can be considered made of hard leather material.

From the above equation,

p T;

With decrease in temperature, pressure also decreases.
