It increases in volume as it rises. The pressure exerted on the bubble is constantly decreasing as the bubble rises.

The bubble's volume increases. Air can usually be considered an "ideal" gas, which behaves according to the Ideal Gas Law, which is: P*V = N*R*T, or V = (N*R*T)/P, where V is the volume, N is the number of gram-moles of the gas, T is the absolute temperature, and P is the pressure. So you can see, as P goes down (the water pressure decreases with decreasing depth), V goes up.

not completely sure but i would think it would get bigger because the closer to the surface you get the less pressure on the sides of the bubble would be. since gas is compressible the size of the bubble can change

It gets larger, as the pressure outside the bubble lessens the air inside can expand.

The bubble will expand, because it has to do with pressure and the deeper you are the more pressure. Think about this if you do not exhale you will have and an embolism!!!!

very good question!!!!!

The bubble will get larger....less water pressure as the bubble rises.

it expands because the pressure of the water is less as it gets closer to the surface.

It gets bigger. Because heat expands.
