Match the substances given in column A with their uses given in column B: A B (i) Gold (a) Thermometers (ii) Iron (b) Electric wires (iii) Aluminium (c) Wrapping food (iv) Carbon (d) Jewellery (v) Copper (e) Machinery (vi) Mercury (f) Fuel

(i) Gold is a highly ductile metal, therefore it is used in making jewellery. (ii) Iron is used for making machinery because we can change the shape of iron to our desirable shape. (iii) Aluminium is highly malleable, hence its foils are used for wrapping food items. (iv) Carbon is a non-metal which is used as fuel. (v) Copper is ductile in nature; therefore, it can be used for making electrical wires. (vi) Mercury is a liquid metal which is used in thermometers.
