State two ways to prevent the rusting of iron.
(N/A) Two ways to prevent the rusting of iron are:
$(i)$ Oiling,greasing,or painting: By applying oil,grease,or paint,the surface becomes waterproof,and the moisture and oxygen present in the air cannot come into direct contact with the iron. Hence,rusting is prevented.
$(ii)$ Galvanisation: An iron article is coated with a layer of zinc metal,which prevents the iron from coming into contact with oxygen and moisture. Hence,rusting is prevented.
