Chapter 9 Adsorption
adsorption onto solid surfaces must include knowledge of “historical” elements. Method for a material to reduce surface energy Liquid: reducing the interfacial area (from spherical drop) Solid: adsorbing materials - heterogeneous in the distribution of excess surface energy, so, the adsorption is not a uniform process.

Otherwise, they are linearly dependent. There is an easier way to see if two functions y 1 and y 2

Thus, finely divided metals and porous substances having large surface areas are good adsorbents.
