Kinetic Theory of Gases · Gas laws and molecular picture

An air bubble of volume 2.9 cm32.9\ \mathrm{cm^3} rises from the bottom of a swimming pool of 5 m deep. At the bottom of the pool water temperature is 17 ∘17\ ^\circC. The volume of the bubble when it reaches the surface, where the water temperature is 27 ∘27\ ^\circC, is cm3\mathrm{cm^3}.
(g=10 m/s2g = 10\ \mathrm{m/s^2}, density of water =103 kg/m3= 10^{3}\ \mathrm{kg/m^3}, and 1 atm pressure is 10510^{5} Pa)
