Question
Why do we apply paint on iron articles?
✓

Answer

Iron objects undergo rusting due to metal corrosion; hence, surface of iron is coated with paint to prevent it from rusting. As a result, iron does not come in contact with air. Thus, iron objects remain safe for longer period and rusting does not оссur.
