no, not really, the reason the bubble floats is because of the hot air slowly moving upward. there are no chemical processes going on
No, it is not a chemical change. For example, if you put gold bubbles into any single acid, no chemical change will take place.
In and of itself, no. Both chemical and physical changes can create bubbles.
An example of a chemical change that produces gas and can be observed as bubbles is the reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid). When these two substances combine, they undergo a chemical reaction that produces carbon dioxide gas, which forms bubbles. This effervescence is a clear indication of the gas being released during the reaction.

No.
It is a chemical change.
air bubbles is a sign that a chemical change has occured
Depending on the chemical change, sometimes color change, or appearance of bubbles.
Not always but they can. They may simply be an indication of a phase change, as when water boils. This is usually counted as a physical change rather than a chemical change. But if you add baking soda to vinegar, you will see bubbles as a result of a chemical change.
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.
Water bubble is a substance not a change.
It is a physical change.
