1. Interfaces

When two phases, generally immiscible liquids, are in contact, the contact area forms an interface.

Definition

The interface is a region of undefined thickness but thin in relation to the surface, through which all exchanges of matter and energy between the two phases in contact take place.

The interface is in a particular state that can be described as a borderline equilibrium.

  • On a macroscopic scale, the interface is considered to be a three-dimensional system with sufficient thickness to allow the macroscopic laws of physics and chemistry to be applied to it. The interface behaves like a continuous medium through which exchanges between systems are governed by global laws.
