Question

Consider a diver who takes a deep breath before entering the water. In this case, the maximum capacity of his lungs, which is three liters, is filled.

Before entering the water, the pressure in the lungs is 101/3 kPa and temperature is 37 degrees Celsius. He then sinks to a depth of 25 meters.

(a) How many moles of air did he breathe?

(b) If the diver does not exhale and the temperature inside the lungs remains constant and the pressure in the lungs is the same as the water pressure in which it is located, what is the volume of the lungs at the desired depth?
