Answer :
(i) Most copper is used in electrical equipment such as wiring and motors. This is because it conducts both heat and electricity very well, and can be drawn into wires.
(ii)Countless objects that simplify as well as increase the quality of our daily life are partly made of aluminum, For example: CDs, cars, refrigerators, kitchenware, electric power lines, packaging for food and medicine, computers, furniture and aircrafts.
(iii) Iron is used primarily in structural engineering applications and in maritime purposes, automobiles, and general industrial applications (machinery).
(iv) Silver is used for jewellery and silver tableware, where appearance is important.
(v)Gold alloys are used for fillings, crowns, bridges, and orthodontic appliances.
(vi)Mercury can be used to make thermometers, barometers and other scientific instruments.
