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?
