A scuba diver 40 ft below the ocean surface inhales 55.0 mL of compressed air from a scuba tank at a pressure of 3.20 atm and a temperature of 7 ∘C. What is the final pressure of the air, in atmospheres, in the lungs when the gas expands to 155.0 mL at a body temperature of 37 ∘C, and the amount of gas does not change?

3) A breathing mixture of oxygen and nitrogen is prepared for a scuba diver who is going to descend 400 ft below the ocean surface. At that depth, the diver breathes a gas mixture that has a total pressure of 8.00 atm. If the partial pressure of the oxygen in the tank at that depth is 1200 mmHg, what is the partial pressure, in atmospheres, of the nitrogen in the breathing mixture?

A scuba tank is filled with air to a gauge pressure of 204 atm when the air temperature is 33 ∘C. A diver then jumps into the ocean and, after a short time on the ocean surface, checks the tank's gauge pressure and finds that it is only 196 atm. Assuming the diver has inhaled a negligible amount of air from the tank, what is the temperature of the ocean water? Express your answer to two significant figures and include...

A scuba diver exhales 3.32 L of air while swimming at a depth of 20.0 m where the sum of atmospheric and water pressure is 2.95 atm. By the time the bubbles of air rise to the surface, where the pressure is 1.00 atm, what is their total volume? Assume the temperature of the water body is uniform.

A scuba diver is 45 m below the surface of a lake, where the
temperature is 5°C. He releases an air bubble with a volume of 10
cm3. The bubble rises to the surface, where the
temperature is 25°C. Assume that the air in the bubble is always in
thermal equilibrium with the surrounding water, and assume that
there is no exchange of molecules between the bubble and the
surrounding water. What is the volume of the bubble right before...
