is rusting tin a chemical or physical property

Toasting bread is a physical property because it involves heating the bread, which does not change its chemical composition.

Slicing bread is also a physical property because it involves physically cutting the bread into smaller pieces, without changing its chemical composition.

Rusting tin, on the other hand, is a chemical property because it involves a chemical reaction between tin and oxygen in the presence of water, resulting in the formation of iron oxide (rust). This changes the chemical composition of the tin.
