Question

Hello, I've been stuck on this question for hours. Can someone help me solve part a, and part b of this questions with steps for referencing back on how to solve this kind of chemistry problem?

Question:

Scuba divers experience increasing pressure as they descend in water due to the extra weight of the water above them. There is an increase in pressure of 1.0 atm for every 33 ft descended. This must be added to the atmospheric pressure of 1.0 atm at the surface because this pressure doesn't go away under water. If we approximate that a human lung expands by 0.50 L per breath, compute the PV work of a lung at:

a. The earth's surface ______ J

b. A depth of 33 ft ______ J

Thank you so much!
