Question

The maximum lung capacity of an average adult is about 4-6 L. A scuba diver takes a breath of about 2.1 L of air at a depth of 30 m where the pressure is 405 kPa. If the diver holds his/her breath while rising to the surface, where the pressure is 102 kPa, what is the volume of air in the lungs? What is the likely result?

Answer 1

PV is constant, so
102V = 405*2.1
