Question

What is the surface phenomena??​

Answer 1

Answer:

the special properties of surface layers, that is, the thin layers of a substance at the boundary of contiguous bodies, mediums, or phases.

Explanation:

Answer 2

Answer:

Surface Phenomena. the special properties of surface layers, that is, the thin layers of a substance at the boundary of contiguous bodies, mediums, or phases.

                      These properties result from the excess free energy of the surface layer and from the special features of the layer’s structure and composition.

                 Surface phenomena are found in any heterogeneous system consisting of two or several phases. In essence, the entire physical world, from cosmic bodies to submicroscopic formations, is heterogeneous. Only systems in limited volumes of space may be regarded as homogeneous. Thus, the role of surface phenomena in natural and technological processes is great. Surface phenomena are especially important in disperse (microhetero-geneous) systems, in which the interphase surface is most highly developed. In fact, the conditions facilitating the appearance and prolonged existence of such systems are related to surface phenomena.
