Question

Explain how to painting of an iron gate prevents it from Rusting​

Answer 1

Answer:

For rusting, the presence of air(oxygen) and moisture(water) is required. Painting prevents direct interaction of iron, air and moisture. Hence, painting of an iron gate prevents it from rusting.

Answer 2

Answer:

Painting an iron gate forms a layer of paint over the iron metal molecules

iron rusts when it comes in contact with oxygen and water and then oxidise to form reddish brown color which we know as rust

painting the iron gate blocks the contact of iron molecules to oxygen present in the air

this prevents rusting
