Good conductors such as iron have free electrons which can move around freely to transfer heat throughout the iron structure. So when iron is being heated, its free electrons vibrate quickly and conduct heat quicker. Iron is a naturally found metal most …

Witryna1 dzień temu · Metals are good conductors of heat by the virtue of free electron availability. They have a regular structure that permits the flow of electrons from one end to another. Metals conduct heat when heated from a point of higher temperature to a point of lower temperature till thermal equilibrium is obtained. Witryna29 cze 2015 · 1 Answer. Electricity needs charged particles (or quasi-particles) to conduct it. Heat can be conducted with almost any quasi-particle. Diamond is one of the best conductors of heat in existence, and it's because of phonons, ie quasi-particles of lattice vibrations, which are strong because the diamond lattice is strong.
