Perfect mixing

"Perfect mixing" is an assumption which states that a certain volume of a substance has such good mixing that it has no spatial variations in temperature, composition, density, or any other property. In other words, all properties of the system are exactly the same at each and every point within the system. This assumption is generally valid for small, well-stirred tanks, as well as gaseous systems.
