1.24 A submarine's main air flasks are recharged to

4500\\\\psi g

while the boat is deep and the seawater temp is

55\\\\deg F

. The boat then comes shallow and enters the Gulf Stream where the seawater temperature is

80\\\\deg F

. Because these flasks are in the main ballast tanks, which are flooded with seawater, assume the air flasks equalize with the new environmental temperature. Also assume that no air is discharged from the flasks during this time. What will the air flask pressure gage read (psig)? What amount of heat was added to the air? Classify the thermodynamic process and explain why this is the correct answer.
