Detailed explanation-1: -Some of the best conductors of heat are Copper, Aluminium, Graphite, Silver, Gold, etc.
Detailed explanation-2: -Metals are good conductors of heat because of the closely packed metallic lattice structure and free electrons. Their free electrons are also responsible for conduction of electricity.
Detailed explanation-3: -Silver: The single most conductive metal, silver conducts heat and electricity efficiently thanks to its unique crystal structure and single valence electron.
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: -Gold conducts heat and electricity. Copper and silver are the best conductors, but gold connections outlast both of them because they do not tarnish.
