An air bubble rises to the surface of a glass of water due to buoyancy. The buoyant force acting on the bubble is greater than the force of gravity pulling it down, causing it to move upwards until it reaches the surface.
The density of water is approximately 1 g/cm3 at room temperature. An air bubble in water doesn't rise to the surface immediately because its buoyant force is not strong enough to overcome the cohesive forces between water molecules, which tend to keep the bubble trapped below the surface. Once the bubble accumulates enough buoyant force or is disturbed, it will rise to the surface.
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 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.
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.
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.

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

When light passes from one medium to another with different densities, such as air to glass, some light is reflected at the interface. This reflection of light creates a silvery appearance on the surface of the air bubble in the glass slab. The color is a result of interference between the reflected light waves.

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.
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.
Condensation on a glass surface occurs when warm, moist air comes into contact with the cooler surface of the glass. The air cools down upon contact with the glass, causing the water vapor in the air to condense into liquid water droplets on the surface of the glass.
Answersoap does float if it is filled with air
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.
