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
Most likely, the water bubbles very much and it might come out of the kettle.
It can . . . bubbles come from oxygen that is dissolved in the water. Pureness has little to do with it, unless the pure water has simply not been shaken up so as to dissolve oxygen into it.
The gas being evaporated forms the bubbles in boiling water.
I am just in Science 1 on FlVS. But if I remember right it is conduction. Conduction is where the moluicules inside move around faster and faster till the cooler part is warm. Now lets use a pot. The pot would start of cool unlike the stove. And it will as I pointed out up there make the pot warm to which will make the water warm and which it starts to boil.I hoped that helped,Logan Church
When a droper is dipped into water and its bulb is pressed air bubbles seems to occur in water because the dropper was filled with air before it was dipped in water and when we press the bulb air comes out forming air bubbles and the space is filled with water .
When you first start to boil water, the bubbles that you see are basically air bubbles. Technically, these are bubbles formed from the dissolved gases that come out of the solution, so if the water is in a different atmosphere, the bubbles would consist of those gases. Under normal conditions, the first bubbles are mostly nitrogen with oxygen and a bit of argon and carbon dioxide. As you continue heating the water, the molecules gain enough energy to transition from the liquid phase to the gaseous phase. These bubbles are water vapor. When you see water at a "rolling boil," the bubbles are entirely water vapor. Water vapor bubbles start to form on nucleation sites, which are often tiny air bubbles, so as water starts to boil, the bubbles consist of a mixture of air and water vapor.

Leaves have gaseous exchange through its stomata or free cell surface (in case of water plants). These gases come out in the form of bubbles in water. Hence air bubbles are formed when leaves are in water.

As the water absorbs heat, at the temperature of 100 degrees Celsius or 212 degrees Fahrenheit, the liquid water boils and becomes a gas. The gaseous water, called "steam", expands and becomes far less dense. The steam bubbles rise to the surface.
The gas being evaporated forms the bubbles in boiling water.
The bubbles have air or some other gas in them that is lighter than water.
The water displaces air, which moves to the top. It comes up through the water layer, creating bubbles.
the water is evaporating which pulls the water into a gas and the air bubbles take up at that space, come to the top, and dissappear so if its out long enough the bubbles might go away
bubbles come up
gas bubbles are created inside you an they come out either way as a burp or gas
That is related to the Law of Conservation of Energy. To boil water, you need to get it hotter, that requires energy, and this energy has to come from somewhere.
