Iron grills are painted to stop exposing them in air why?
Answers
Explanation:
An iron grill is painted frequently to prevent its rusting. (b) There is less corrosion of aluminium than iron when both are exposed to air because aluminium forms a layer of aluminium oxide on its surface as soon as it comes in contact with moist air
Answer:
Iron grills react with certain gases in the air to form oxides.This leads to rusting of the grills.if the grills are rusted then they become weak in nature and cant hold the structures that they hold properly
hence sometimes we see that old materials of iron which is rusted tend to break
rusted iron is also dangerous when it hurts any part of our body
hence in order to prevent all this grills are painted
after painting,iron articles dont rust easily
