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 of the above

Text Solution

Verified by Experts

The correct Answer is:

C

The first two methods cannot be used to protect a frying pan because both grease and paints are organic matter which burn on heating. Therefore, a coating of zinc is usually applied. Zinc being more reactive than Fe does not allow rusting to occur.
