You are wearing scuba gear and swimming under water at a depth of 66.0 ft. You are breathing air at 1.50 atm and your lung volume is 10.0 L. Your scuba gauge indicates that your air supply is low so, to conserve air, you make a terrible and fatal mistake: you hold your breath while you surface. What happens to your lungs?

Consider these questions in order to answer that question: What does Boyle’s Law say about what happens to gases when pressure is reduced? How would that affect a flexible closed container?

By the way, the number given for gas pressure at depth (1.5 atm) does not seem to jibe with the depth (66 ft).
