Match the columns. Metal Use a) copper i) making jewellery b) gold ii) filament in bulb c) mercury iii) coating taps d) chromium iv) building bridges e) iron v) thermometer f) tungsten vi) electrical wiring

Copper is a very good conductor of electricity and is therefore used in making electrical wires. Gold is a lustrous and malleable metal and is thus used in making jewellery. Mercury is the only metal that is in liquid state at room temperature and is thus used in thermometers. The coating of chromium prevents the water taps from rusting, thus, it is used in the coating taps. Iron is a very hard and strong metal and is therefore used in the construction of bridges. Tungsten is used in the filament of bulb because it is the metal with a very high melting point.
