| If the pore size approaches the size of a molecule, then surface diffusion in which adsorbed molecules move along the pore walls, becomes the dominant diffusion mechanism.

| Since access of the ambient fluid to the heated surfaces is restricted, some of the heated surface is starved of cool ambient to which heat can be transferred.
