One can calculate this quantity from the Clausius Clapeyron equation given the vapor pressure and heat of vaporization. A mixture for which this property is lower than for either of the constituent parts is called a positive 
One can calculate this quantity from the Clausius Clapeyron equation given the vapor pressure and heat of vaporization. A mixture for which this property is lower than for either of the constituent parts is called a positive azeotrope. This property can be bypassed by a process analogous to supersaturation, which can lead to violent eruptions upon adding nucleation sites. This colligative property can be defined as the temperature at which the vapor pressure is equal to ambient pressure. For ten points, name this phase transition which involves changing from a liquid to a gas, and happens in water at 100 degrees Celsius.
