No. The aluminum is reacting with the acid; it is a chemical change.
It is a physical change.
The bubbles themselves are physical. What caused them might have been a physical change or a chemical change; it's impossible to say without more information.
In and of itself, no. Both chemical and physical changes can create bubbles.

Water bubble is a substance not a 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.

If you ae talking bubbles released from a can of soda = physical. It is just carbon dioxide being released. If you are talking bubbles produced from a mixture of baking soda and vinegar = chemical. It is actually changing the chemical composition and releasing oxygen from the H2O.

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.
A physical reaction is when no new substances are formed, there is a change of state eg ice melting to a liquid. A chemical change is when the reaction forms a new substance. eg gas bubbles. An acid reaction can be both. You need to look at the reaction taking place, look for change of state (physical) or any colour change or gas bubbles (chemical).
