Examples of chemical changes are BURNING, cooking, rusting, and rotting. Examples of physical changes are boiling, MELTING, freezing, and shredding.Galvanization or GALVANIZING (also spelled galvanisation or galvanising) is the process of applying a protective zinc coating to steel or iron, to prevent rusting.
