TOPIC 8: Heat Transfer
Conduction takes place through 2 processes:
1. Transfer of Molecular Vibration; and
2. Diffusion of Free Electrons.
In metals (which have free electrons), conduction takes place through both processes; but in non-metals (which do not have free electrons), conduction takes place only through transfer of molecular vibration.
