Interface (matter)

In the physical sciences, an interface is a surface forming a common boundary among two different phases of matter, such as an insoluble solid and a liquid, two immiscible liquids, a liquid and an insoluble gas or a liquid and vacuum. The importance of the interface depends on the type of system: the bigger the quotient area/volume, the more effect the surface phenomena will have. Therefore, interfaces are very important in systems with big area to volume ratios, such as colloids. One important interface is the gas liquid interface between aerosols and other atmospheric molecules.
