Question

rusting of iron is a chemical change but magnetization of wire is a physical change why give reason​

Answer 1

Answer:

Rusting of iron is oxidation of iron from Fe to Fe2O3 and is an irreversible process. hence a chemical change. Whereas, iron bar gets magnetised only when it is in vicinity of a magnet and is a reversible process, hence it is a physical change.

Answer 2

Hey dear ur answer is here.....

Rusting of iron is oxidation of iron from Fe to Fe2O3 and is an irreversible process. hence a chemical change. Whereas, iron bar gets magnetised only when it is in vicinity of a magnet and is a reversible process, hence it is a physical change.
