TOPIC 8:    Heat Transfer

Tip 1:

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.
