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,

The bubbles come from the bottom, because it is the hottest part, as it contacts the heating element.
They contain some air that was dissolved in the water, but if the water is actually boiling, the main constituent of the bubbles is steam.
They are bubbles of water vapour forming at the bottom of the pan where the heat is greatest.
These bubbles contain air.
The gas being evaporated forms the bubbles in boiling water.
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 main difference between boiling and evaporation is that boiling is much faster. Boiling also often takes place at the bottom of the fluid (where the heat source usually is) whereas evaporation takes place only at the surface. So boiling can produce bubbles, while evaporation doesn't.Evaporation is the process by which molecules in a liquid state (e.g. water) spontaneously become gaseous (e.g. water vapor), without being heated to boiling point. It is the opposite of condensation. Generally, evaporation can be seen by the gradual disappearance of a liquid, when exposed to a significant volume of gas.Boiling is very rapid evaporation starting within a container of water.Normally evaporation occurs at a much slower rate than boiling because most evaporation occurs with room temperature water.Boiling occurs only when the liquid is heated to the boiling point, and vapor bubbles come from the bulk of the liquid. In evaporation, vaporization occurs only at the surface of the liquid, not throughout the liquid, and this occurs at lower temperatures.
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 .
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.

Secret compartment
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
The gas that you see coming out of water when it is boiling is water vapour being produced because the temperature and pressure are right at a given point in time. Air in water such as the bubbles you see collect on objects submerged in water or the air that fish breathe is dissolved into the water at point of contact.

bubbles come up
It is NOT a chemical reaction. Boiling is a physical reaction. When heat is applied to water in a pot, the hydrogen and oxygen molecules begin to get excited; they bounce around everywhere. The heat traps the oxygen molecules in bubbles, which go to the sides of the pot (following the path of least resistance). These bubbles then come to the surface, releasing oxygen and steam. Boiling is simply a phase change from a liquid to a gas.
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.
The "air bubbles" are gases that are dissolved in the water. When the ice freezes the gas make the unfrozen water more concentrated with the dissolved gases until it becomes saturated and then comes out of solution and gets trapped in the surrounding ice. If you look at an ice cube you will notice that bubble are located in the centre which is the last place in the cube that freezes. If you make ice cubes from freshley boiled water you will not get the bubbles as boiling the water forces any dissolved gases to come out of solution and the ice cubes will be perfectly clear.
