(Absolute zero is -457.) A football is filled to a gauge pressure of 15.8 psi when its temperature is 80.
(Absolute zero is -457.0 F.)
A football is filled to a gauge pressure of 15.8 psi when its temperature is 80.0°F. (Gauge pressure is the difference between the actual pressure and atmospheric pressure.) After the ball has cooled to 58.8°F.
(a) Assuming that the volume of the football does not change, and that air behaves as an ideal gas, find the gauge pressure of the air in the football. (Answer in psi)
