 State two ways to prevent the rusting of iron.

Answer 1

Methods of preventing the rusting of iron:
(a) The rusting of iron can be prevented by painting, oiling, greasing or varnishing its surface.
(b) Galvanisation is another method of protecting iron from rusting by coating it with a thin layer of zinc.

Answer 2

Rusting of iron can be prevented by the following two ways:

1. By coating the surface of iron with paint: On coating, air and moisture cannot comes in contact with iron and hence, no rusting takes place.
2. By applying grease or oil on the surface of iron: This method also prevents air and moisture to come in contact with iron and hence, no rusting takes place.
