1. Interfaces
When two phases, usually immiscible liquids, are in contact, the contact zone is called an interface.
Definition
The interface is a region of ill-defined thickness, but small in relation to the surface, through which all exchanges of matter and energy take place between the two phases in contact.
The interface is in a particular state that can be described as boundary equilibrium.
On a macroscopic scale, the interface is considered to be a three-dimensional system of 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.
