A scuba tank when fully charged has a pressure of 180 atm at 18°C. The volume of the tank is 11.3 L.

(a) What would the volume of the air be at 1.00 atm and at the same temperature?

(b) Before entering the water, a person consumes 2.0 L of air in each breath, and breathes 12 times a minute. At this rate, how long would the tank last?

(c) At a depth of 23.0 m in sea water at a temperature of 10°C, how long would the same tank last assuming the breathing rate does not change?
