After the 2015 afc championship football game between the new england patriots and the indianapolis colts, it was alleged that the new england patriots had under inflated eleven of their twelve footballs. nfl rules require that the footballs be inflated between 12.5 and 13.5 psi and the pat's footballs were under by ~2 psi. claims were made that the lower pressure was due to the change in temperature from the locker room were the footballs were initially inspected and the cold field where the game was played. assuming that the footballs were properly inflated to the minimum pressure, 12.5 psi, in the locker room where it was 76.5°f (24.7°c), what would the temperature, in °c, have been on the field to explain a loss of 2 psi in pressure.
you will need to assume no change in the volume of the football and no leaks which may or may not be true.

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
