What do you call material that does not let heat through easily?
A insulator (a thermal insulator)
A conductor is a material that can transfer energy efficiently and and insulator is the opposite. Conductor means something that blocks it and insulator means something that can go through it A conductor easily transfers energy in the form of electricity and/or heat, while an insulator does not easily transfer these types of energy. In electricity, a conductor is a material that can let current pass through and an insulator does not let current pass…
Any material which has high thermal conductivity can easily transfer energy as heat. As far as I know, all metals have high thermal conductivity. Copper, gold and silver especially have high thermal conductivity. Diamond and graphene have VERY high thermal conductivity, so this is not restricted to only metals.
there are many ways we can transfer the energy from one material to other and it can be easily done through heat energy to electrical and other is vice-versa. Radiant energy (radiation) Heat conduction (travelling heat) Convection (currents of warm air) Electrical power transmission Mechanical work (machines)
