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.

Answer

 

Corrosion can be prevented by

  • by greasing the surface 

But, incase of a frying pan, 

(a) grease can not be used to prevent rusting of a frying pan because it may spoil the food.

(b) paint can not be used to prevent rusting as the fry pan is heated and washed , the paint can come off .

Hence, (c) galvanising ( applying a coating of zinc) is the most suitable method to prevent rusting in this case.
