Question 10
State two ways to prevent the rusting of iron.

Open in App
Solution

Two ways to prevent the rusting of iron are:

  • Oiling, greasing, or painting: By applying oil, grease, or paint, the surface gets a waterproof coating and the moisture and oxygen cannot come into direct contact with the iron article. Hence, rusting is prevented.
  • Galvanization: An iron article is coated with a layer of molten zinc metal that prevents the iron article to come in contact with oxygen and moisture. Hence, rusting is prevented.
