Question

give two points why silver is the best conductor of heat but cannot be used in electrical wires​

Answer 1

Answer:

Though Silver is a very good conductor of electricity but still that is not used in electric wiring primarily due to its cost. It's very expensive compared to the widely used wiring material copper. Another reason for not using Silver is that, it oxidizes easily and tarnishes when it comes in contact with air.

-> Its very expensive compared to the widely used wiring material copper.

-> Its oxidizes easily and tarnishes when it comes in contact with air.More tarnishing generate more heat and turn it can cause fire as well.
