In metals, few of the electrons are not fixed to one atom they normally move freely between atoms. This is the main reason that the metals are good conductor of heat and electricity. In other words if one side of the metal is hot and the other end of the metal is cold, then the electrons present on the hotter end have more thermal energy than the cold end. So as the electrons move freely they transfer energy from the hotter side to the cooler side.

The speed of the heat conduct depends upon many factors such as:


  • Number of free electrons.

  • Speed of the moving electron.

  • Distance the electron can cover before they bump into something.
