. A “diving bell” is an apparatus that was used before the invention of SCUBA to inspect underwater structures. It consists of a platform inside a chamber or bell. The entire apparatus can be lowered, trapping air in the chamber so a person can breath as shown in the figure below. When the platform is at the free surface (h = 0) the air in the chamber is at atmospheric pressure and a temperature of 15?C. Assuming the initial volume of air in the chamber is 10m3 , and the temperature of the air does not vary, find

• The pressure in the air chamber when the platform has been lowered to a depth of h = 5m

• The volume of the air at this same depth.

A primitive diving bell consists of a cylindrical tank with one end open and one end closed. The tank is lowered into a freshwater lake, open end downward. Water rises into the tank, compressing the trapped air, whose temperature remains constant during the descent. The tank is brought to a halt when the distance between the surface of the water in the tank and the surface of the lake is 35.0 m. Atmospheric pressure at the surface of the lake...

A diving bell is a 3.4 m -tall cylinder closed at the upper end but open at the lower end. The temperature of the air in the bell is 30 ∘C. The bell is lowered into the ocean until its lower end is 100 m deep. The temperature at that depth is 10∘C. a) How high does the water rise in the bell after enough time has passed for the air to reach thermal equilibrium? Express your answer to two...

A SCUBA tank, an air tank used for breathing under water, is initially filled with gas at a pressure of 2.8x107 Pa and 32 oC. The tank has a volume of 11.5 L. If the tank will continue to provide air until it reaches a pressure of 1.2x106 Pa, how many moles of gas will it provide to a diver diving in water at 10 oC? Give your answer in moles to at least three significant figures. Hint: There will...

A SCUBA tank, an air tank used for breathing under water, is initially filled with gas at a pressure of 2.3x107 Pa and 25 oC. The tank has a volume of 16.0 L. If the tank will continue to provide air until it reaches a pressure of 2.5x106 Pa, how many moles of gas will it provide to a diver diving in water at 6 oC? Give your answer in moles to at least three significant figures. Hint: There will...

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...

Chapter 5- Gases 24. As weather balloons rise from the earth's surface, the pressure of th atmosphere becomes less, tending to cause the volume of the balloons to exand. However, the temperature is much lower in the upper atmosphere that at sea level. Would this temperature effect tend to make such a balloon expand or contract? Weather balloons do, in fact, expand as they rise. What does this tell you? 37. Freon-12 (CF2Cl2) is commonly used as the refrigerant in...
