Question

give reasons why

copper metal is used for making wires

and graphite is used for making electrode in dry cells

Answer 1

Dear student!

a).Copper is good conductor of electricity, heat resistant and ductile in nature and also cheaper than the other metals which does not undergo rusting very easily, so it is used in making electric wires.

b). Graphite is an allotrope of a non metal called as Carbon, which acts as semi metal and so unlike the other non metals it is a good conductor of electricity and it is most stable form of carbon under standard condition so , it is used as anode where carbon rod or carbon electrode is required for reaction.
