Estimates of the enthalpy change associated with this process may be found using the reduced temperature by the Watson relation or by assuming a constant value for the entropy change by Trouton's rule.
Estimates of the enthalpy change associated with this process may be found using the reduced temperature by the Watson relation or by assuming a constant value for the entropy change by Trouton's rule. That enthalpy change is proportional to the derivative of the vapor pressure with respect to the inverse of temperature by the Clausius-Clapeyron equation.  A binary mixture which does not change composition under this process is called an azeotrope. In one of the colligative properties, the temperature at which this process occurs is increased. This process occurs when the vapor pressure is equal to the atmospheric pressure. For 10 points, name this phase change from a liquid to a gas.
