ABSTRACT
In the case of partial or complete wetting the situation is very much different. In this case, adsorption of water molecules on the solid substrate results in lowering of the solid–vapor interfacial tension and even more than that, the adsorption results in polymolecular adsorption, that is, in a formation of thin adsorption water film on the solid substrate. There is no need to say that the interfacial tension cannot be refereed to any more as solid–vapor interfacial tension in this case but rather solid–liquid film-vapor interfacial tension. Usually low volatility means liquids with big molecules; the latter means high viscosity and correspondingly higher time-scale of equilibration process with the oversaturated vapor. All properties of water and aqueous solutions are vitally important for our life. The latter means that the peculiar shape of the disjoining pressure of water and aqueous solutions, presented in some way determines the existence of life.
