Question

for every 10 m you descend below the surface of water, the pressure on you will increase by an amount equal to atmospheric pressure 101kpa. an air bubble in a lake has a volume of 20 mm^3 at a depth of 40m. predict what volume it will have just before reaches the surface?

Answer 1

at surface pressure = 1 atm

gains 4 atm so at 5 atm at 40 m

pressure is 1/5 so volume is 5 times at surface

Answer 2

Yes
