Because it just does
The bubbles at the bottom of the pot are called boiling bubbles. They form when water reaches its boiling point and releases steam.
Boiling is not as fine a process as it might seem. Evaporation increases gradually until boiling is reached. Boiling occurs when there is sufficient heat to immediately turn the water to its gaseous state. The bubbles you see forming at the bottom of a pot for example are water vapor having been boiled to gas and tend to form at the bottom because that is where it is hotter- near the heating source. You'll see steam coming off of heated water but the bubbles that are forming during boiling are water being turned to gas. Essentially the bubbles are a less intense form of boiling. As you get hotter water the bubbles will form more rapidly and will "boil" as you're more familiar with it.
No, air bubbles will not appear when reheating boiled water. The boiling process releases dissolved gases, so when the water is reheated, there are no air bubbles left to be released. The lack of dissolved gases makes it appear that air bubbles do not form when the water is reheated.
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.
When detergent is added to boiling water, it can cause the water to foam up and create a lot of bubbles. This is because the detergent molecules decrease the surface tension of the water, causing bubbles to form more easily. However, adding detergent to boiling water shouldn't have any harmful effects and is commonly done during cooking or cleaning processes.
What you mostly see in the bubbles is steam, which is water in gas form.
Dissolved air bubbles out of the water, as the boiling point of water is reached, water vapour starts to form inside the liquid in the form of bubbles
The bubbles at the bottom of the pot are called boiling bubbles. They form when water reaches its boiling point and releases steam.
Boiling water does not separate hydrogen from oxygen; it merely converts water (H₂O) from liquid to gas through the process of vaporization. The bubbles you see in boiling water are primarily water vapor, which is water in its gaseous form. These bubbles form when water reaches its boiling point, causing it to turn into steam. The molecular structure of water remains intact during boiling.
Water vapor (steam) is inside the bubbles that form inside boiling water. The bubbles that form prior to boiling are mostly dissolved gases escaping from the water.
Small bubbles start to form at around 160°F (70°C) in water as it begins to heat up and reach its boiling point of 212°F (100°C). These bubbles form at the bottom of the pot and rise to the surface as the water nears the boiling point.

The bubbles in boiling water are made of water vapor, which is the gaseous form of water. As the water heats up, it turns into steam and creates bubbles that rise to the surface and eventually burst.

well it depends if you boil it over a fire sometimes bubbles do occur but if your just heating it at a temperature lower than boiling than it just slowly evaporates like regular water in a lake
