An air bubble of volume 15 cc is formed at a depth of 50 m in a lake. If the temperature of the bubble while rising remains constant then what will be the volume of the bubble at the surface?(Given: g=10 m/s2 & atm. pressure = 1.0 * 100000 Pa)

p1V1 = p2V2,
ρgh V1 = p2V2,
V2 = ρgh V1/ p2,
ρ = 1000 kg/m^3 is the density of water,
p is the atm. pressure
