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.

What happen to gas bubble volume as they rise in water?
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 does an air bubble rise to the surface of a glass of warter?
When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid. When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air.
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 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.
How does mercury in thermometer rise and fall?
When it heats, it expands and then it risesup the narrow glass tube. when it cools, it contracts and falls down. gallileo made one that used a bubble in water and traveled up and down a swell

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 air sink in water?
No air or any form of gas will always rise to the surface (as a bubble)

When you fill a glass of water from a faucet and then let the glass sit undisturbed for 2 hours you will see small bubbles sticking to the glass what are the bubbles why did they form?
The short answer is due to imperfections on the surface of the glass "seeding" bubbles out of the water. What is meant by "seeding" this means is that when a gas is dissolved in a solution (like the small amount of air in tap water), it remains within the solution in microscopic bubbles. If there is an area where these microscopic bubbles can gather, they will do so to create a larger bubble (due to the hydrophobic effect). Areas that promote these microscopic bubbles to gather are called "seeds". Eventually the bubble will be too large to simply stay in solution and begin to rise to the surface, often as a visible tiny bubble. This is the same reason why after pouring yourself a glass of your favorite carbonated beverage, you may see small bubbling trails seemingly coming from the side of the glass out of nowhere. The "source" or origin of the bubbling is likely a small imperfection of the glass seeding bubbles. The bubbles clinging to the surface of the glass is the same thing, but on a smaller scale since there is less gas dissolved in tap water, than in a carbonated beverage.

What are examples of adhesion and cohesion?
cohesion: water's cohesion causes molecules on the surface of water to be drawn inward, which is why drops pf water form beads on a smooth surface. adhesion: adhesion between water and glass causes water to rise in a narrow tube against the force of gravity ice formingon the surface of water bodies in winter
What causes bubbles to rise on top of water?
The gas inside the bubble is less dense than the surrounding water

How does a Navy sub launch its missiles?
The missiles are pushed out of their silos with compressed air and rise to the surface literally in a bubble of air. Very little seawater comes into contact with the missile until it breaks the surface of the water. The missile is ignited at the surface and the guidance system steers it to it's target.
