Question
Problem 13.28 Part A A scuba tank is filled with air to a gauge pressure of 201 atm when the air temperature is 27 C.A diver then jumps into the ocean and, after a short time on the ocean surface, checks the tank's gauge pressure and finds that it is only 196 atm. Assuming the diver has inhaled a negligible amount of air from the tank, what is the temperature of the ocean water?

P1 = initial pressure = 201 atm
T1 = initial temperature = 27 C = 27 + 273 = 300 K
P2 = Final pressure = 196 atm
T2 = Final temperature = ?
using the equation
P1 /T1 = P2/T2
201/300 = 196/T2
T2 = 292.54 K = 19.54 C
