  • How is coal energy transferred to energy by

    2009-11-2 · Conduction: The Coal energy is transferred by conduction, convection and radiation. Conduction happens in solids because they are good conductors. This happens by the particles moving quickly they begin to hit each other and the energy moves through them causing the energy to pass through the solids, this is able to happen easily because of free electrons.
