Mention any two ways of preventing iron from rusting.

Rusting is the name commonly used to describe the corrosion of iron. When iron is exposed to oxygen and moisture, over time, it converts to iron oxides and loses its metallic character. Rusting can take place on pipes, ships and any other iron object. There are a number of ways we can protect iron objects from rusting. Galvanization is a commonly used method to protect pipelines carrying water from rusting. In the process of galvanization, a thin layer of zinc is coated over the iron metal thus breaking the contact between iron and air. Galvanized pipes are also known as GI or galvanized iron pipes. GI pipes are commonly used for water supply connections at residential and commercial buildings. Another commonly used method is the application of paint over the iron objects. Paint is commonly used on iron doors and windows to protect them from rusting. The idea here is to prevent any contact between the metal and air and moisture.

Hope this helps.
