GCSE P1 1.1.3 Energy Transfer by Heating
... In the marble, the thermal energy is transferred from particle to particle. Particles at the hot end vibrate more strongly and this increased vibration is slowly passed onto neighbouring particles along the length of the rod. Copper contains free electrons and these provide an additional thermal ene ...
