Pretty sure it's called it's Boiling Point. This happens when you've put enough heat energy into the substance to change it into a gas. An example might be liquid water which you heat until it boils to make water vapour. Water vapour and all other elements you heat will have the same name (like water is still H2O, no matter what form it's in) but it will have a little g next to it, meaning gaseous.
For example:
Water + heat = H2Og
It's a bit more complicated at higher levels because you have to consider the air composition but it works as an explanation.

When bubbles form during a reaction, it is typically called effervescence. This occurs when a gas is produced as a byproduct of the chemical reaction, causing bubbles to be released.
Bubbles forming on heated water are usually due to the process of water vaporization rather than a chemical reaction. When water is heated, the molecules gain energy and move faster, eventually reaching a point where they break free from the liquid surface and form bubbles of water vapor. This phase change is a physical process, not a chemical reaction.
The beginning compounds of a chemical reaction are called reactants. Reactants are the substances that react with each other to form products during a chemical reaction.
Bubbles can form in ice when gas, such as air or carbon dioxide, gets trapped during the freezing process. As the water freezes, it expands and can entrap the gas within the ice, forming bubbles.
The formation of bubbles of hydrogen gas when drain cleaner is added to water is a chemical reaction. The reaction between the chemicals in the drain cleaner and water produces hydrogen gas as a result of a chemical reaction, which is a rearrangement of atoms to form new substances.
Bubbles can form in hydrilla due to a process called pearling, which occurs when the plant photosynthesizes and releases excess oxygen as small bubbles. These bubbles cling to the leaves and stems of hydrilla, giving it a bubbly appearance. This can be a sign of healthy and active plant growth.
