Question

Write a short note on rusting and its methods of prevention.​

Answer 1

Answer:

When a piece of iron is left out in open for a while a film of brownish

substance gets deposited on its surface called rust. Rusting occurs when iron is

exposed to oxygen in air and water or water vapours. This process of rust

formation in presence of oxygen and water or water vapours is called rusting.

Some ways to prevent rusting are:

1.Paint the surface of the metal with any durable acrylic paint.

2. Avoid contact of metal surface with moisture or water.

3. Coat the metal surface with oil, grease.
