Question 10:
State two ways to prevent the rusting of iron.
Answer
Two ways to prevent the rusting of iron are:
(i) Oiling, greasing, or painting: By applying oil, grease, or paint, the surface
becomes water proof and the moisture and oxygen present in the air cannot
come into direct contact with iron. Hence, rusting is prevented.
(ii) Galvanisation: An iron article is coated with a layer of zinc metal, which prevents
the iron to come in contact with oxygen and moisture. Hence, rusting is prevented.
