A bubble of air escaping from a diver's mask rises from a depth of 155 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 ml 2. The density of mercury is 13.6g mL 47 times larger Use your answer to explain why scuba divers constantly exhale as they slowly rise from a deep dive. Since the pressure decreases by a factor of approximately 46 the volume must increase : by a factor of approximately 47 Divers exhale to decreases the amount of gas in their lungs, soit does not expand : to a volume larger than the diver's lungs.

Question
A bubble of air escaping from a diver's mask rises from a depth of 155 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 mL! 2. The density of mercury is 13.6 g mL 47 times larger Use your answer to explain why scuba divers constantly exhale as they slowly rise from a deep dive. Since the pressure decreases by a factor of approximately factor of approximately 47 the volume must Increase : by a Divers exhale to decreases the amount of gas in their lungs, so it does not expand : to a volume larger than the diver's lungs.
