Definition of molecular diffusion

Molecular diffusion is also called molecular mass transfer, or diffusion for short, which is the phenomenon of mass transfer due to the irregular thermal movement of molecules. Diffusion is related to temperature, and is a basic method of mass transfer. It is the phenomenon of material migration in space due to the thermal movement of molecules, atoms, etc. under the effect of concentration difference or other driving forces.
