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 222atm at the start of the dive. The air temperature at the surface is 85?F and the diver ends up in deep water at 55?F.
Part A Assuming thermal equilibrium and neglecting air loss, determine the absolute internal pressure of the air when it is cold.
