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.
Beating aluminum to make aluminum foil is a physicalchange, and not a chemical one. Note, however, that aluminum is generally rolled to make foil rather than beaten. The ductility of aluminum is a physical characteristic of this amazing metal that makes it possible for us to do that.
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.
No you can not make aluminum foil change colours. Because it is already galvanised all chemical colour changing will not work because the aluminum is coated.
No, titanium is not tin. Titanium (chemical symbol Ti) and tin (chemical symbol Sb) are both chemical elements. They are unique. They have different physical and chemical properties, and links are found below that you can follow to investigate the two substances.
Physical. It's still aluminum foil.
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.
Foil cut into pieces represents a physical change.
it's a physical change.
Physical. It's still aluminum foil.
It is a physical change because it can be reversed. All you have to do is weld the foil back together!
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.

whats the balanced chemical equation
Chemical
· Absorption of water into a towel · Crumpling a piece of paper · Pulling copper into a thin wire - a change of shape, but not a change of composition · Cutting a material such as wood · Tearing a piece of tin foil
