It is a chemical change, because a new substance is created, and you cannot reverse it back to the way it was.
Aluminum bending is a physical change. This is because the aluminum is still the same aluminum as it was before just in a different shape.
It's a chemical change. The aluminum foil is rusting, which cannot be undone, meaning that this is a chemical change, not a physical. Physical changes can be reversed.
Crushing an aluminum can is a physical change because you have only changed its shape, but not its chemical composition.
It is a chemical reaction. Hint: if it has the word "reaction" it. it's probably a chemical process.
If the aluminum bubbles it will be a chemical change.
This is a chemical change.

Dissolving in water is a physical change.

Crushing an aluminum can is a physical change because you have only changed its shape, but not its chemical composition.
It is a physical change because it can be reversed. All you have to do is weld the foil back together!
When you combine them it is a chemical reaction (change) yes, but them combined in a solution is a physical change.
