diving bell is a 4.8m -tall cylinder closed at the upper end but open at the lower end. The temperature of the air in the bell is 30 degrees celcius. The bell is lowered into the ocean until its lower end is 100 m deep. The temperature at that depth is 10 degrees celcius 1. How high does the water rise in the bell after enough time has passed for the air to reach thermal equilibrium? 2. 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?
