Question

Is aluminum rusting physical or chemical change

Answer 1

Chemical because it can not be changed like cutting a piece of paper

Answer 2

Rusting is a chemical change . 

My reason being is because the physical shape and structure of the object doesn't change.

The color , appearance , or look may change and if that happens than its a chemical change.

Example :

Since the aluminum is rusting it probably turned red or orange , but the shape and size is still the same.

I really hope that this helps you out a lot , have a nice day.
