Solution:
The above statement is true.When iron is exposed to water and moisture, rust is formed. Iron reacts with water and moisture during rusting and gets covered by a brown layer with different chemical properties from iron. The formation of rust is a chemical change because rust is a different kind of matter than the iron, oxygen, and water present before the rust formed. The iron reacts with oxygen in the presence of moisture from the brown layer of iron. This brown layer is called rust and is a hydrated form of iron (III) oxide. Rusting removes a material layer from the surface and weakens the material.
