This equation of state of the mixture is called the lever rule. [5] [6] [7] The dotted parts of the curve in Fig. 1 are metastable states. For many years such states were an academic curiosity; Callen [8] gave as an example, "water that has been cooled below 0°C at a pressure of 1 atm. A tap on a beaker of water in this condition precipitates ...
