An air bubble has a volume of 1.75 cm3 when it is released by a submarine 125 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.(adsbygoogle = window.adsbygoogle || []).push({});

P= a+h*g*density

a=101325Pa

h=125m

g=9.8

density of freshwater=1000kg/m^3

P1*V1=P2*V2

1326325Pa*1.75cm3=101325*V2

V2=22.90cm3?

when calculate the initial pressure i get 1326325Pa so that would be the pressure under the water and the pressure above the water would just be 101325Pa?

Am i doing this right?
