A diving bell in the shape of a cylinder with a height of2.80 m is closed at the upper end andopen at the lower end. The bell is lowered from air into sea water(ρ = 1.025 g/cm3). The air in the bell isinitially at 15.0°C. The bell islowered to a depth (measured to the bottom of the bell) of42.0 fathoms or 76.8 m. At this depth the water temperature is4.0°C, and the bell is in thermal equilibrium with the water.
(a) How high does sea water rise in the bell?
m
(b) To what minimum pressure must the air in the bell be raised toexpel the water that entered?
atm
