This is rather complicated, as it involves work being done by the force of buoyancy. One way to look at this is to imagine the bubble as a balloon having a negligible weight relative to the weight of the air it contains. In air, this imaginary balloon weighs nothing because (by Archimedes Principle) it is buoyed up by a force exactly equal to the weight of the air it displaces. Now submerge this "balloon" in water. So long as it is submerged, the "balloon" will experience a buoyancy force upward (i.e., towards the surface of the water) equal to the weight of the water it displaces minus the weight of the air due to gravity. The buoyancy force (Fb) will accelerate the air in the bubble at a constant rate upward. Since work is equal to force times distance, the amount of work, W, done in moving the air in the bubble from some submerged position, xo, to a position at the surface, xs, will be W=Fb *(xs-xo). The difference in position is just the depth, d, of the bubble relative to the water surface, so W=Fb*d. One can regard this quantity as the potential energy, PE, of the submerged air bubble: PE=Fb*d.
If we correctly note that the weight of the air in the bubble is insignificant relative to the weight of the water it displaces, we can say that PE is equal to the weight of the water that is displaced times the depth of the bubble. (The depth of the bubble is the depth relative to the center of the sphere described by the bubble.) This is the energy that will be imparted to the air in the bubble as it rises in the water. Conversely, this is also how much energy it will take to move the bubble from its position at the water surface to a certain depth.
Things get really complicated as the bubble emerges from the water, because the buoyancy force reduces from the weight of the displaced water to zero, but this will usually be a very small effect.
What else can I help you with?
Why do air bubbles in water rise to surface?
Consider the total gravitational potential energy of the water/bubble system. Since water is more dense than air, the bubble has less mass than the equivalent volume of water. So, if the bubble could rise a little the increase in potential energy of the air would be more than compensated for by the decrease in potential energy of the water. This (rather simple) argument shows that the total potential energy of the system decreases as a function of the bubble's height, and thus the bubble rises through the water. More generally, it predicts that any object placed into a fluid of greater density should rise.
Why an air bubble in water burst as it emerges on water surface?
An air bubble in water bursts at the surface due to a decrease in surface tension. As the bubble rises, the water surrounding it is dragged along, stretching and thinning the surface layer. When the bubble reaches the surface, this thin layer breaks, causing the bubble to burst.
Is Niagara falls a good example of kinetic energy being converted to potential energy?
Yes, Niagara Falls is a classic example of kinetic energy being converted into potential energy. As the water flows down the falls, it gains speed and kinetic energy, which is then converted into potential energy as the water rises higher above ground level.
What kind of energy does water at the top of a dam?
Potential.
How does air bubble inside the water behave and why?
When an air bubble is released underwater, it will rise to the surface due to buoyancy. Buoyancy is the upward force exerted by a liquid on an object immersed in it. As the air bubble rises, the water pressure decreases and the bubble expands in size until it reaches the surface.
When an air bubble rises in water what happens to its potential energy?
no matter what happens to the bubble, even if it sinks or rises, the mass will remain the same throughout. we all know that as we go deeper into water, the pressure increases with the depth. hence, when the bubble rises, the pressure exerted on it decreases and simultaneously, the volume increases. that is all that happens to the bubble. the mass remains constant unless it bursts. the mass of air in the bubble originally is now dissolved in the water. always remember that the mass of anything is constant as long as it is acted upon the same gravitational force.

Buoyancy.

Why do molecules rise when they get warmer?
Because the water molecules which are far inside the liquid experience an outward force, and has no maximum potential energy.
Why is hydropower potential energy?
The potential energy in this system is the column of water stored behind the dam. This water has the potential to have its energy turned into electric power.
What kind of energy does water at the top of a dam?
Potential.

Does water have energy?
Yes, water has energy in the form of kinetic energy and potential energy. Kinetic energy refers to the energy from water molecules moving, while potential energy refers to the energy stored when water is held at a certain height.
Is a glass of water sitting on a table potential energy?
No, a glass of water sitting on a table does not have potential energy. Potential energy is the energy an object has due to its position or state, such as when the glass of water is raised above the table.
Is water flowing from a waterfall before it hits the pond below kinetic or potential energy?
is water real
