Solution
Corrosion:
Corrosion is defined as a process where materials, usually metals, deteriorate as a result of a chemical reaction with air, moisture, chemicals, etc.
For example, iron, in the presence of moisture, reacts with oxygen to form hydrated iron oxide.
$4Fe + 3{O_2} + n{H_2}O \to \mathop {2F{e_2}{O_3}.n{H_2}O}\limits_{Hydrated\,\,iron\,\,oxide} $
This hydrated iron oxide is rust.
