Give reason.
An iron article should be given a coat of paint
Advertisements
उत्तर
Iron articles often undergo rusting, resulting in the formation of a reddish-brown layer on their surface. Rusting is caused by the exposure of iron to the air and water in the surroundings. An iron article that is coated with paint prevents the interaction of iron with the surrounding air and water and thus protects it from rusting.
