Answer:
Explanation:
(i) No, we cannot protect the articles permanently
from rusting by painting on them.
(ii) The method of painting is suitable for short time.
(iii) If there is a scratch on the paint on the surface
of the article and if a small surface of the metal
comes in contact with air, the process of rusting
starts below the layer of the paint.
