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.
Bubbles usually indicate a chemical change because they are often a result of a reaction that creates a gas as a product. This gas being released as bubbles can suggest that new substances are being formed during the chemical reaction.
Yes and no.
Bubbles of carbon dioxide effervescing from a soft drink is a physical change.
Bubbles of carbon dioxide produced as vinegar reacts with baking soda is a chemical change.
I believe Any change to the state of a substance (gas to liquid ad vice versa) is chemical. Air bubbles are a result of a gas being formed from a liquid. Therefor yes, it's a chemical change.
Bubbles indicate either an increase in heat causing one of the reactants to boil or the production of a gas. Both of these are indications of a chemical reaction.
Yes, gas bubbles indicate the solutions molecules have broken down and reformed, some into a new molecule, others into a gas.

Is bubbles a chemical change?
In and of itself, no. Both chemical and physical changes can create bubbles.
Is it a physical or chemical change champagne bubbles when the cork is removed?
It is a physical change.
What change in a physical property of matter can indicate?
A change in a physical property of matter can indicate a physical change, such as a change in state (solid to liquid), color, shape, or texture. These changes do not alter the chemical composition of the substance.
Is bubbles when aluminuim wire is dropped into HCL a physical change?
No. The aluminum is reacting with the acid; it is a chemical change.
When acids are added to rocks containing a carbonate bubbles form is this evidence of a physical change or chemical change?
This is evidence of a chemical change. When acids react with carbonate minerals in rocks, they create gas (CO2), which leads to the formation of bubbles. This reaction results in the formation of new substances, indicating a chemical change.
Do the bubbles in a pot of boiling water for noodles indicate 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.
Is bubbles a chemical change?
In and of itself, no. Both chemical and physical changes can create bubbles.
Is it a physical or chemical change champagne bubbles when the cork is removed?
It is a physical change.
What change in a physical property of matter indicate?
a physical change or a chemical change
Are water bubbles chemical or physical change?
Water bubble is a substance not a change.
Baking powder bubbles and gives off CO2 when it is moistened is it a chemical or physical change?
It is a chemical change.
What change in a physical property of matter can indicate?
A change in a physical property of matter can indicate a physical change, such as a change in state (solid to liquid), color, shape, or texture. These changes do not alter the chemical composition of the substance.
When baking soda is mixed with lemon juice bubbles are formed with the evolution of gas Is it a physical or chemical change?
it is a chemical change
Is bubbles fizzing a physical or chemical change?
Physical. If a substance releases bubbles, it is converting some of its liquid into a gaseous state. The chemical properties do not change, only its present state. A most common physical change is that of watching ice melt in glass of water.
Is bubbles when aluminuim wire is dropped into HCL a physical change?
No. The aluminum is reacting with the acid; it is a chemical change.
Why does the sound of thunder indicate a physical change rather than a chemical change?
