Why does an air bubble formed in water grow in size as it rises from the bottom to the surface? Explain.
(N/A) The pressure exerted by the water column decreases as the bubble rises from the bottom towards the surface because the depth of the water column above the bubble decreases.
According to Boyle's law,for a given mass of gas at a constant temperature,the volume $V$ of the gas is inversely proportional to the pressure $P$ $(V \propto \frac{1}{P})$.
As the pressure $P$ decreases while the bubble rises,its volume $V$ must increase to satisfy the relationship.
Therefore,the air bubble grows in size as it moves towards the surface.
