Question

An iron article should be given a coat of paint.

✓

Answer

When an iron article is kept for long time it gets corroded due to presence of oxygen in atmosphere.
Iron gets oxidized to iron oxide which forms a reddish brown layer on it and iron gets rusted.
It is called corrosion. Due to corrosion things become weak.
So an iron article should be given a coat of paint so that it is protected against corrosion.
Paint gives protection to iron.
