Homework Statement
A scuba diver releases a 2.50-cm-diameter (spherical) bubble of air from a depth of 11 m in a lake. Assume the temperature is constant at 16.0ºC, and the air behaves as a perfect gas. How large is the bubble when it reaches the surface?
Homework Equations
V2 = V1*(T2 / T1)*(P1 / P2)
The Attempt at a Solution
T1 = 16.0ºC + 273.15 = 289.15 K
V1 = 4/3 * [tex]\pi[/tex] * r[tex]^{2}[/tex] = 8.18 cm[tex]^{3}[/tex]
But how do I find P1 and P2? Please help.
