Question

diamond is bad conductor of electricity but good conductor of heat

Answer 1

Diamond is a bad conductor of electricity but good conductor of heat. Electricity is conducted in a crystal by electrons that are relatively free. But in diamond, each carbon atom is covalently bonded with four other carbon atoms and there are no free electrons.

Answer 2

Answer:

✮requried answer:

Since the conduction of electricity requires the presence of free electrons, diamond is a bad conductor of electricity. But conduction of heat does not require the presence of free electrons, so diamond is a good conductor of heat
