An air bubble has a volume of 1.51 cm3 when it is released by a submarine 102 m below the surface of a lake. What is the volume of the bubble when it reaches the surface? Assume that the temperature of the air in the bubble remains constant during ascent.

P*V = constant as the bubble rises
Calculate the initialtofinal pressure ratio.
That equals the final/initial volume ratio.
