Question:

State two ways to prevent the rusting of iron.

Answer:

The rusting of iron can be prevented by:

(i) Painting or Oiling: By applying paint or oil on the surface becomes waterproof and the moisture and oxygen present in the air cannot come into contact with iron. Therefore, rusting can be prevented.

(ii) Galvanisation: An iron article is coated with a layer of zinc metal, which prevents the iron from coming in contact with oxygen and moisture. So, rusting is prevented.
