Physical Changes in metal are: melting bending and rusting
Rust (oxidation of metal) is a chemical change but it is also a physical change in the strength of the material.
Rust (oxidation of metal) is a chemical change but it is also a physical change in the strength of the material.
The rusting metal of the chain is chemical and the towel that is now wet is physical. The water is still water but the metal is now been oxidized.
A nail rusting is a chemical change. The chemical formula of the metal completely changes, adding oxygen to the formula. Iron changes from Fe to FeO2 , or to Fe2O3
Rusting is a chemical change, as steel/iron turns into iron oxide.
no
Rusting is a chemical property because it is irreversible. It changes the identity of the substance.
no rusting iron is not a physical change it is a chemical change
No but it helps prevent chemical changes like rusting.
