Question

(e) Metals are bad conductors of heat​

Answer 1

Answer:

Metals are good conductors of heat. There are two reasons for this: the close packing of the metal ions in the lattice. the delocalised electrons can carry kinetic energy through the lattice.

hope it helps u..a little bit...

Answer 2

Answer:

This is due to the way that metals are chemically bonded: metallic bonds (as opposed to covalent or ionic bonds) have free-moving electrons which are able to transfer thermal energy rapidly through the metal. Lead lacks this kind of electrons so it's a poor conductor of heat.
