State 2 properties of each of the following metals which make them suitable for:-
(i) Copper and aluminium for making electric wires.
(ii) Gold, Platinumand Silver are used to make jewellery
(iii) Copper to make hot water tank.
1) The copper and aluminum are good conductor of electricity in which the aluminum is more preferred these days as it contains high tensile strength and ductility than copper so used for electrical transmission lines. They are of light weight and tensile nature which is preferable for electric
2) Platinum, gold, and silver are used to make jewellery because they are very lustrous. Also, they are very less reactive and do not corrode easily.
3) Copper is a metal that does not react with water, but the oxygen of the air will react slowly at room temperature to form a layer of Copper oxide on Copper metal due to which it doesn't corrode easily.
