Question

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

• A. Applying paint
• B. Applying a coating of zinc
• C. All of these
• D. Applying grease

Answer 1

The correct option is B Applying a coating of zinc

Applying paint and grease are not suitable solutions to prevent an iron frying pan from rusting as the paint and grease can spoil the food cooked.
We can prevent iron getting rusted by applying a coat of zinc. Galvanisation is a method of protecting steel and iron from rusting by coating them with a thin layer of zinc.
