1.	Name the method which can prevent rusting ? plzz give me answer
Answer» tion:Galvanising is a method of RUST prevention. The iron or STEEL object is coated in a THIN layer of zinc. This stops oxygen and water reaching the metal UNDERNEATH - but the zinc also acts as a sacrificial metal . Zinc is more reactive than iron, so it OXIDISES in preference to the iron object.
