Detailed explanation-1: -Some of the best conductors of heat are Copper, Aluminium, Graphite, Silver, Gold, etc.
Detailed explanation-2: -Diamond is the leading thermally conductive material and has conductivity values measured 5x’s higher than copper, the most manufactured metal in the United States. Diamond atoms are composed of a simple carbon backbone that is an ideal molecular structure for effective heat transfer.
Detailed explanation-3: -Metals are good conductors (both of heat and electricity) because at least one electron per atom is free: i.e., it is not tied to any particular atom, but is, instead, able to move freely throughout the metal.
Detailed explanation-4: -Metals are excellent conductors of electricity and heat because their atoms form a matrix through which outside electrons can easily move. Instead of orbiting their individual atoms, they generate a sea of electrons around the positive nuclei of the interacting metal ions.
Detailed explanation-5: -Graphite (an allotrope of Carbon) is a non-metal that is a good conductor of heat and electricity.
