Question

why do surface phenomena not possible in gas - gas bulk phases​

Answer 1

Explanation:

In many important surface phenomena, such as heterogeneous catalysis or passivation of the surface by suitable protective coatings, the chemical composition of the topmost layer controls the surface properties and not the composition in the bulk.

Answer 2

Explanation:

Explanation:Evaporation is a surface phenomenon because, during evaporation, the molecules with higher kinetic energy dissipate into the air from the topmost layer of the liquid so it is a surface phenomenon.jsh
