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.
Air is lighter than water, so the air bubbles just float to the top.
Because a gas is less dense than water and air in solution will rise to the surface.
Because aisn't as dense as water causing it to rise
Density. The gas comprising the bubble is less dense than the liquid in which is it suspended.
Because air is less dense than 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.
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.
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.
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
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.

No air or any form of gas will always rise to the surface (as a 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.
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.

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.
NOOOOO!!!!!!Girl awnser-If you fart in a pool then a bubble will get stuck in your bikiny and it will look like you poo'd your pants.Boy awnser-if you fart in a pool the bubble will rise out of your trunks and slowly jiggle up to the surface. When it does get to the top it will smell soooo bad it will kill everyone.

Uually the only time you see this is in old glass. This is just old glass that was made by a less refined process and occasionally bubbles appeared in the glass. Some people actually search for windows of this vintage.
