insulator
Copper cables are reputed to carry electricity well.
An insulator.
Metals are known to be good conductors of heat as well as good conductors of electricity. Diamond is an exception though, being one of the best thermal conductors but a very poor electrical conductor.
The heat will transfer from the hot material to the cold material. Heat tends to go where it is not.

Metals conduct heat and electricity well.
polystyrene foam cups and composite Wood material like snake glass fiber etc
A material with a good thermal conductivity or a thermal conductor.
Copper cables are reputed to carry electricity well.
convection currents
A good type of material that transfers heat or electricity well.
