Adsorption. is the accumulation of atoms or molecules on the surface of a material. This process creates a film of the adsorbate (the molecules or atoms being accumulated) on the adsorbent's surface. It is different from absorption, in which a substance diffuses into a liquid or solid to form a solution. The term .

Intermolecular forces between the molecules in the bulk experience equal pull on all sides, resulting in a net force of zero. However, molecules at the surface (or interface) experience a significantly greater “pull” from the molecules below them in the liquid than from the gas molecules above them. The net force results in a “pull” towards the bulk liquid (known as surface tension).. M.E. (08214). MECHANICAL ENGG.DEPT.. IISc. ME-255. Principles . of tribology. Wear .

Therefore,. conduction in a fluid can be viewed as the limiting case of convection, corresponding to the case of quiescent fluid (Fig. 6–1).. Nimesh Gajjar. CONVECTIVE HEAT TRANSFER. . Convection heat transfer involves . fluid motion . heat conduction. The fluid motion enhances the heat transfer, since it brings hotter and cooler chunks of fluid into contact, initiating higher rates of conduction at a greater number of sites in fluid. Therefore, the rate of heat transfer through a fluid is much higher by convection than it is by conduction. In fact, the higher the fluid velocity, the higher the rate of heat transfer..
