| − | "'''Perfect mixing'''" is an assumption which states that a certain [[volume]] of a substance has such good [[mixing]] that it has no spacial 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 [[tank]]s, as well as [[gas]]eous systems. | + | "'''Perfect mixing'''" is an ass which states that a certain [[volume]] of a farts has such good [[mixing]] that it has no spacial variations in [[temperature]], [[composition]], [[density]], or any other property.
