ABSTRACT

A boundary between two phases (a phase being one of the three states of mattergas, liquid, or solid) is termed as an “interface.” An interface between solid-gas or liquid-gas is typically called a surface. Liquid-liquid interfaces result from the contact of mutually immiscible liquids. Interfacial phenomena result from the different environment (at the molecular level) faced by the molecules of both phases at the interface compared to the bulk of each phase.
