  • Heat Conduction
    • Conduction of heat is the process where vibrating particles pass on their EXTRA KINETIC ENERGY to neighbouring particles.
      • This process continues throughout the solid and gradually, some of the extra kinetic energy/ heat is passed all the way through the solid,causing a rise in the temperature at the other side of the solid. And hence an increase in the heat radiating from its surface.
    • Metals conduct heat so well because the electrons are free to move inside the metal.
      • At the hot end, the electrons move faster and collide with the other free electrons, transferring energy. These other electrons then pass on their extra kinetic energy to other electrons.
        • Because the electrons are free to move, this is obviously a much faster way of transferring the energy through the metal, than slowly passing it between jostling neighbouring atoms.
          • This is why heat travels so fast through metals.
