Explanation:

The Science Behind Rusting

Iron, as well as iron alloys, rusts because of a chemical reaction known as oxidation. When iron is exposed to moisture or oxygen, oxidation occurs. During this chemical reaction, iron is converted into iron oxide.

☞ Rust occurs when iron or its alloys, such as steel, corrode. The surface of a piece of iron will corrode first in the presence of oxygen and water. Given enough time, any piece of iron will change entirely into rust and disintegrate.

ᢰ The process of rusting is a combustion reaction, similar to fire. Left in contact with oxygen, iron will react with the oxygen to form rust. Unlike fire, though, the reaction is much slower and does not create a flame.

ᢰ There are certain factors that can speed up the rusting process. For example, water speeds up the reaction. Other substances, such as salt, can also increase the speed of the rusting process.

$\Large{\green{\tt{\underline{\underline{Methods \ to \ prevent \ rust }}}}}$

↣ To prevent rust, iron can be coated. This prevents its reaction with oxygen and water. One such process is called galvanization. This usually involves coating an iron object with a layer of zinc. The zinc helps to stop the iron from reacting with oxygen and water to form rust.

↣ Another method of preventing rust is much simpler and common. What is it? Paint! That’s right. A simple coat of paint can prevent iron from reacting with oxygen and water in the environment.
