As a bubble rises to the surface of a liquid the pressure on it is going DOWN. Therefore the bubble expands, and usually bursts at the surface.

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.
What is the meaning of water density?
Density is mass per unit volume of a substance. The Mass and volume of water is in the ratio of 1:1 .There fore the density of water is 1. With rise and decrease of temperature the volume increases or decreases to change the water density.
Why do air bubbles in water rise?
Bubbles are comprised of gases, which have a lesser density than water. Since they are less dense, they get pushed up to the surface, and they rise, lighter than the liquid around them.
Why do balloons rise in the air?
A balloon rises in the air only if the balloon has a lower mass than an equal volume of the air surrounding it.That might be the case if the balloon were filled with a light gas such as helium, for example. The balloon rises because the pressure of the air around it pushes it up in the same way that water causes an air bubble to rise.
Why does an air bubble rise to the surface of a glass water?
The deeper you go under water the higher the pressure due to the weight of water above. Therefore the pressure of the water at the level of the bottom of the bubble is higher than the pressure at the level of the top of the bubble. The unbalanced force forces the bubble up. In all mixtures of (non-reacting) fluids and gases, the higher the density of a component, the lower it lies. Anything that has a density less than 1g/cm cubed (water density) floats but if it has a higher density than water then it sinks.

Why a small bubble rises slowly through a liquid whereas the bigger bubble rises rapidly?
The strength of the buoyancy of a bubble is in proportion to it's volume. Since a larger bubble has more volume, as a rule, it would rise more rapidly than a small one.
What are facts about a dry ice bubble?
Assuming the bubble occurs in water then the bubble contains almost pure CO2. It should be cooler than the water. and it will rise tothe surface.

Does volume of water affect temperature rise in reaction between calcium oxide and water?
If lots of water is added then the temperature will rise
What causes bubbles to rise on top of water?
The gas inside the bubble is less dense than the surrounding water
Does air sink in water?
No air or any form of gas will always rise to the surface (as a bubble)
Does the volume of water affect the temperature rise in the reaction of calcium oxide and water?
If the volume of water increases the tempreture change will also increase.
What is the Archimedes principle of displacement?
I think it is the volume displacement. When you put an object into a container with a known volume of water, the water will rise, and that change of volume is the volume of the object you introduced into the container.
Does the volume of water increase when you add a solid?
The water level of the container will rise, and the total volume increases. But the volume of the water itself remains the same.
Why does the water level rise when you drop a pebble in a jar half full of water?
pebble has volume so water rises equal to volume of pebble
