Which of the following methods is suitable for preventing an iron frying pan from rusting?

  • (a) Applying grease
  • (b) Applying paint
  • (c) Applying a coating of zinc
  • (d)All the above


Answer :

The most suitable way of preventing an iron frying pan from rusting is applying a coating of zinc. This process is also called galvanisation.


Applying grease(a) and applying paint(b) are also one of the ways to prevent iron frying pan from rusting but it is not the most best possible way as grease and paint can be eroded/removed while heating or cleaning iron frying pan but on the other hand coating of zinc will be sustained for a longer duration.
