Boundary surface

As Boundary surface designates one in that the surface, the two separates. The distinction between bordering and surfaces is historically conditioned and purely arbitrary. As under normal conditions boundary surfaces are designated firmly and liquidgaseously.

The atoms or molecules, of which the phases are composed, are to be be usually energetically unfavorably, in the proximity of the boundary surface, there them there smaller for as inside their phase experience. From this a grenzflaechenspannung results, better admits than .

like Detergenzien, Tenside, soaps, emulsifying agents reduce the surface tension and promote the mixing of the two phases.
