A diving bell is a 3.0-m-tall cylinder closed at the upper end but open at the lower end. The temperature of the air in the bell is 20C. The bell is lowered into the ocean until its lower end is 100 m deep. The temperature at that depth is 10C. a. How high does the water rise in the bell after enough time has passed for the air inside to reach thermal equilibrium? b. A compressed-air hose from the surface is used to expel all the water from the bell. What minimum air pressure is needed to do this?
