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)

p1•V1 = p2•V2,

ρ•g•h• V1 = p2•V2,

V2 = ρ•g•h• V1/ p2,

ρ = 1000 kg/m^3 is the density of water,

p is the atm. pressure

take p1= ro*g*h + p atmospheric

then u will get it:

(10^3*10*50+10^5)15=10^5*v

v=90cc

njoy...:)
