A scuba diver has an air tank with a volume of 0.0200m3 . The air in the tank is initially at a pressure of 1.00 x 107Pa. Suppose that the diver breathes 0.300L/s of air. Note diver is in fresh water.
1. Discover how long the tank will last a depth of 1.00 m
2. Discover how long the tank will last at a depth of 10.0m
