They are boiling. In other words they are turning from a liquid in the a gas. The bubbles are formed by the gas escaping.

When a liquid is heated, air dissolved in it comes out in the form of bubbles. After some time the bubbling stops.

Liquids bubble when they are heated because they are boiling. Boiling is the process through a liquid changes into a gaseous state. So, this bubbles could be formed by the highly energetic particles of the liquid that are escaping into the atmosphere from the liquid surface. Im not sure...but this is my guess.

Because of flow patterns, transient phenomena and local conditions. Some points in the liquid may reach the boiling point locally. These bubbles are the liquid evaporating and turning into the vapor or gas.
Sometimes, it could be that gases dissolved in the liquid decide to take a walk out when it starts to get hot around.

when the catalyst "heat" reacts with the liquid, its state of matter changes into a gas. The molecules are breaking away from each other, causing bubbles. Molecules are close together in a solid form(ice), loose in a liquid(water), and free in a gas (steam)

When things heat enough, they can change into their gasseous state. What you're seeing is the bubbles formed by the gas created by the liquid you are heating. The gas is less dense, and so rises to the surface of the liquid.

a liquid when heated bubbles because when it is in liquid state it has gases dissolved... so as the rule is when temperature increases solubility of gases decreases and thus the gases dissolved start to escape and come out in the form of bubbles when a liquid is heated.

When heating a vessel with water, the hotest bottom making the liquid to boil first and liquid phase is chaning to gaseous phase by breaking of hydrogen bonding between water molecules. These gaseous water molecules (created at bottom) escapes upward from due to their lesser density. At surface straight away evaporation of gaseous water molecules are happening. Hence, bubbling of liquid occurs.

The element that is being heated is transforming into a gas. Being that gas in lighter than the liquid state and that it is heated gas it rises and excaps.
The gas forms at the bottom of say a pot and rises due to the heat being at the bottom.
Huuu and ****.

well i am not sure but this is my gues
wen you boil something, the heat like takes the air out of the water. just like wen you fart in a poil or bubble your milk, th air rises.
another ges is that the heat like containes air. then the air goes through the water with the same result.
