Question

Why do we paint iron grills?
What is crystallization?​

Answer 1

☆ ANSWER ☆;-

1} An iron grill is painted frequently to prevent its rusting.

2} Crystallization or crystallisation is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.

Answer 2

Answer:

1) An iron grill is painted frequently to prevent its rusting. 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.
