Explanation:

When iron items like tawa, pan or nails are left exposed to humid atmosphere, you can find reddish brown coating on them.

The cause behind this is the process of oxidation.

Oxygen present in the air in the presence of moisture or water vapor reacts with iron to form iron oxide which is called rust.

This forms a reddish brown coating on the iron objects.
