Tearing an aluminum foil is a physical change. This will only alter the physical features of the foil and not have any effect on the chemical composition.
Some examples of physical change include melting an ice cube, chopping wood, and breaking a piece of glass. Additional examples include tearing a piece of paper, combining water and sand, and boiling water.
Malleable, brittle, ductile
Iron rusting = chemical gasoline burning = chemical cutting a piece of wood = physical aluminum reacting with foil paper= chemical Anytime the basic molecule is changed, it is chemical, and if it is not than it is physical. Keep in mind that basic state changes (e.g. melting from solid to liquid) are physical.
Crumpling tin foil is a physical change. This process alters the shape and structure of the foil without changing its chemical composition. The material remains aluminum regardless of its form, and no new substances are created during crumpling.
Crumpling tin foil is a physical change, not a chemical change. This process alters the shape and texture of the foil but does not change its chemical composition. The material remains aluminum regardless of how it is manipulated, meaning no new substances are formed.

A piece of aluminum foil has a fixed mass and volume, it is flexible, and it is a metal that can conduct electricity.

Foil cut into pieces represents a physical change.
The physical change of making foil into a ball involves shaping and compressing the foil. By rolling and compacting the foil into a ball shape, its appearance and form are altered without changing its chemical composition.
Cutting aluminum foil in half is a physical change. A physical change alters the form of a substance without changing its chemical composition. In this case, the aluminum foil remains aluminum foil after being cut in half, just in two smaller pieces. No new substances are formed during this process, so it is considered a physical change.
physical change, because you are changing the physical property of the object. you are causing the change by hammering it. If you were to put some kind of chemical on it and it changed the physical property of the object that would be a chemical change.
