उत्तर
Galvanisation is a process in which a thin layer of zinc metal is deposited on iron objects. This is done to prevent iron from rusting by protecting it from contact with air and moisture. Zinc metal, being more reactive, reacts with air to form a hard layer of zinc oxide, which prevents air from passing through it.
