Question

Explain how painting of an iron gate prevents it from rusting.

How does the painting of an iron object prevent its rusting?

Answer 1

Moisture (water) and air (oxygen) aid rusting. By painting an iron gate, we prevent its contact with the air and moisture present in the atmosphere.

Answer 2

• The regular method used to prevent rusting of iron objects is painting the surfaces of iron objects. Rusting takes place in the presence of both air and water.
• Thus, when a layer of paint is applied to the surface of an iron object, it prevents the contact of air and moisture with the iron surface and avoids the rusting of iron objects.
