1.	To prevent rusting, a later of `underline("zinc")` metal is applied on iron sheets.
Answer» Explanation: Due to moisture and various components of atmosphere, oxidation of iron takes place. A certain type of raddish coloured solid layer collects on the iron surface. This layer is called rust. Its chemical formula is `Fe_(2)O_(3).xH_(2)O.` To avoid rusting, a layer of zinc metla is applied on iron sheets which prevents iron sheets from directly coming in contact with the atmosphere and hence, prevents rusting. This process of giving a thin coating of zinc on iron to protect it from rusting is called galvanisation.
