A scuba diver descends to 8.2 m below the surface of the ocean.

(a) What pressure will her regulator need to supply so that her lungs can fill as normal?

(b) When the diver is at 8.2 m, how many times more molecules of air are in her lungs than at the surface? Treat air as an ideal gas and assume the temperature is the same in both instances, which will be somewhat less than body temperature.
