Question
A bubble of air escaping from a diver's mask rises from a depth of 159 ft to the surface where the pressure is 1.00 atm. Initially, the
bubble has a volume of 10.0 mL. Assuming none of the air dissolves in the water, how many times larger is the bubble just as it reaches
the surface?
Use this data:
1. The density of seawater is approximately 1.025 g mL1
2. The density of mercury is 13.6 g mL-1
times larger
Use your answer to explain why scuba divers constantly exhale as they slowly rise from a deep dive.
Since the pressure
by a factor of approximately
i
, the volume must
by a factor of approximately
i
Divers exhale to
the amount of gas in their lungs, so it does not
to a volume
than the
diver's lungs.
eTextbook and Media
Hint
Assistance Used
Pressure is inversely proportional to the volume.
Set up P1V1 = P2V2 and solve for V2 after you determine the pressure at 159 feet below the surface.
