Heat energy flows from a hot medium to a cooler medium.      The transfer of heat through an object without the object itself moving is called conduction.     Conduction is the process of transfer of heat, this happens when one end of a conductor is        heated, the atoms gain kinetic energy and start to vibrate passing on their vibration energy to        neighbouring atoms.      All metals are good conductors of heat.     Higher tier only:        The reason copper is a good conductor of heat is that it has many free moving electrons. When        heated, the electrons move faster and diffuse quickly through copper.
