its because the water on the bottom of the pot, closest to the heating element, boils first, and turns to steam, the bubbles are actually steam trying to escape from the weight of the water above it

As said above the bubbles are steam escaping to the air. Also remember that steam has about 1000 times more volume than the same mass of water. i.e. 1 liter of water would produce 1000 liters of steam at normal atmospheric pressure. That is why the volume of water in a pan appears to not go down over a short period of time (a few minutes).

No, the water interior the air is technically a gasoline. I had this good comparable question as quickly as I found out those products. not ALL water boils at a hundred Celsius. purely whilst subjected to a rigidity of a million environment from our surroundings does it boil at a hundred Celsius. At decrease pressures, water boils at decrease temperatures. the relationship is a complicated function called the Clausius-Clapeyron, or changed simply by fact the Antoine equation. there is actual foundation to the Clausius-Clapeyron equation, yet there is not actual foundation to the Antoine equation. The Antoine equation is greater of a "curve in good shape" attempt at matching experimental data, to account for gentle deviations from the Clausius-Clapeyron equation. The water interior the air isn't warmer than a hundred Celsius, yet quite it fairly is warmer than its boiling component at a decrease rigidity. it isn't the majority rigidity of gasses that set the area of the components, it fairly is the partial rigidity of each and every person constituent. in case you examine up on the billiard ball style of gasses (officially called the kinetic molecular thought), you would be able to work out why it fairly is authentic. If there is purely a million% via molecule volume of water molecules interior the air (that's a typical humidity), the rigidity off of which its boiling component is predicated upon this partial rigidity of 0.01 atm. i've got faith the boiling component of water at 0.01 atm is approximately 6 Celsius if I remember properly. So at any temperature warmer than 6 Celsius, as much as a million% of the molecules of the air would be water.

When you heat water, it looses its ability to absorb air, so some it will bubble out.
Most of the bubbles you see from boiling water are steam, though.

when water is boiling it is heated to the point of the transition from liquid to gas...so that is steam vapor escaping from the liquid you are seeing in bubble form

When liquids turn into gases, change states, the newly formed gases have to have somewhere to go.
