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.
