Solid surfaces (walls of vessels, dust particles) in contact with saturated vapour are usually covered with a rather thick adsorption layer of the liquid phase (“wet”). An oversaturation of the vapour by a decrease of temperature (undercooling) or increase of pressure is therefore impossible, since the wet surfaces act as condensation nuclei which start to grow if one tries to oversaturate the vapour [27.1].
