When a U.S sub Squalus became disable at a depth of 80m, cylinderical chamber was lowered from a ship to rescue the crew. The chamber had a radius of 1.0m abd height of 4.0m, was open at the bottom and held two rescuers. It slid along a guide cable that a diver had attached to the hatch on the sub. Once the chamber reached the hatch and clamped to hull, the crew could escape into the chamber. During the descent, air was released from tanks to prevent water from flooding the chamber.
a. What is the air volume in the chamber at the surface?
b. If the air had not been released from the tanks, wha

Use ideal gas law to find changes in volume.  Sea pressure increase 44 psig for every 100 ft in water depth.
