The burner heats up when electricity or gas is supplied to it. This heat is then transferred to the bottom of the pot through conduction, causing the molecules in the pot to vibrate and generate heat, which cooks the food inside the pot.
A simple way to determine when water is around 95 degrees Fahrenheit is to use a kitchen thermometer. Alternatively, you can look for small bubbles forming on the bottom of the pot, which is a sign that the water is close to reaching boiling point.
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.
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.
No, the bubbles in boiling water for noodles do not indicate a chemical change. The bubbles are formed due to the physical process of water reaching its boiling point and turning into steam bubbles. This is a physical change, as only the state of the water molecules is changing, not their chemical composition.
The bubbles that rise from the bottom of a pan of boiling water are called water vapor bubbles. As the water heats up, it turns into steam, forming bubbles that float to the surface.
When water boils, the bubbles are made of water vapor. Water is changing from the liquid phase to the gas phase, but it doesn't change all at once, so you get bubbles of gas inside the liquid. The phase change will happen first at the location where heating is taking place, so if you have a pot on a stove, the bubbles will form at the bottom of the pot, and then rise to the top.
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

The bottom of a pot is commonly referred to as the "base" or "bottom." In cooking terminology, it may also be called the "cooking surface," where the heat is applied. In some contexts, the term "core" might be used, especially in cookware that has a layered construction for better heat distribution.
hot air. ^^Close. It is actually steam or the gaseous form of H2O (water). As the water is heated it changes from a liquid to a gas. Since the heat is coming from the bottom (in a pot) and the top of the water is cooler, the gas forms bubbles.

there is a pot like thing on the bottom and bubble blower stick thingies dunk in it then the bubble blower stick thingies move up and and air from inside blows and makes bubbles
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.

Bubbles can form at the bottom of a river due to gases, such as methane or carbon dioxide, being released from decomposing organic matter in the sediment. These gases can get trapped under the water and eventually rise to the surface as bubbles.
