A scuba tank initially has a pressure of 180 atm at 20◦ C. The volume of the tank is 11.3 L.

(a) What volume of container (in liters) would be required to store the gas at 1.00 atm at the same temperature?

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

(c) At a depth of 20.0 m, the pressure is approximately 3 atm and the temperature is 10◦ C. How long would the same tank last assuming the breathing rate (2.0 L/breath) does not change?

At rest, the average person breathes 0.5 liters (0.017 ft3) approximately 12-20 per minute. If you were to breath 0.5 liters per breath at a rate of 20 breaths per minute, calculate how long a completely full 80 ft3 scuba tank would last at the following depths – 10 m, 20 m, 30 m, 40 m. Technical divers can also breath mixed gasses to depths below 100 m. Using the same breathing volume and rate, calculate how long it would...

2. An aluminum scuba tank, which has an internal volume of 11.1 L, is filled with air to a pressure of 3000 psi when at room temperature (i.e. 20.0 OC). A diver takes the tank into seawater, where the water temperature is 46 degrees Fahrenheit (i.e. 8.00OC). To what pressure does the air in the tank drop? (The thermal coefficient of expansion for aluminum is 24.0x10-6 OC -1 .) Answer: 2880 psi Please show steps and pictures!

4. The diver in Problem 2, while underwater at a depth of 20.0 m, breathes from the tank so that the air entering the diver’s lungs is at the same pressure as that of the surrounding water. If each breath fills the diver’s lungs to a volume of 3.70 L, and the air he breathes warms to a temperature of 30.0OC, how many breaths can the diver take before the air remaining in the tank drops to a pressure of...

A scuba diver takes a tank of air on a deep dive. The tank's volume is 10 L and it is completely filled with air at an absolute pressure of 237 atm at the start of the dive. The air temperature at the surface is 85 ?F and the diver ends up in deep water at 60 ?F. Assuming thermal equilibrium and neglecting air loss, determine the absolute internal pressure of the air when it is cold.
