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.
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?
