Exercise 60

A scuba diver takes a tank of air on a deep dive. The tank's volume is 10 L and it is completely filled with air at an absolute pressure of 232 atm at the start of the dive. The air temperature at the surface is 94°F and the diver ends up in deep water at 60°F. Assuming thermal equilibrium and neglecting air loss, determine the absolute internal pressure of the air when it is cold.
