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.
A heated liquid has a high temperature. Temperature is the measure of the average kinetic energy of molecules in a substance. The kinetic energy of the air in the bubbles allows them to move fast enough to break free of the surface of the liquid.
The bubbles you see in water are air bubbles. they rise to the top then pop when they reach the surface.
Why does the ground bubble when I water my yard plants? Makes me wonder what is underneath in my back yard. Hmmm.....

Boiling Point
yes it would because when the liquid boils the entire container of liquid is heated to the boiling point, meaning that the liquid would turn to the vapor form all around the liquid.
Gas... bubbles are formed when water (or another liquid substance) are heated up and then turned to gas. When water on a fire heats up at the bottom of a container that water turns to gas before the water at the top. Since gas is lighter than water it rises in the form of a bubble and pops at the surface. So bubbles are in the state of gas, surrounded or covered by a 'membrane' (a thin cover) of liquid
Air bubbles need a surface to cling to. Believe it or not, the surface of a plastic straw is not as smooth as you might think. You cannot see the roughness of the straw but it is enough for the bubbles to cling to and form there. The surface of a glass is usually smoother than a straw so bubbles have a harder time forming there. They just want to slide up the side of the glass to the top.
Without detergent it does not. If you add something like washing up liquid to heated water you can get good bubbles (too watery and they won't have the strength to grow well)
bubbles rise to the surface of a heated liquid as it changes to gas because they are less dense than the liquid.
I am not sure but I think its boiling, hope this helped :)
its still liquid but its starting to form into gas

As heat increases the surface tension decreases.
When water boils, the heat converts some of the water to steam and each bubble is a steam bubble. Steam is a gas that is lighter than water, and so the bubbles rise to the surface of the water where the steam is released. As the steam cools in the air, it forms water vapor, and that is what we see. Most people call the vapor "steam", but steam is a transparent gas, like air.

Since the bubbles have less density than the surrounding water, gravity pulls the water down, and the bubbles go up.

They are regions (bubbles) of gaseous water (water vapor) that have been heated from liquid to gaseous state (having reached the boiling point at 100 deg Celsius).
