The boiling and recondensation of a mixture of two solvents are changes of chemical state; as such, they are best illustrated with a phase diagram. If the pressure is held constant, the two variable parameters are the temperature and the composition. The adjacent diagram shows a positive azeotrope of hypothetical constituents, X and Y.
Boiling-point diagram. The preceding equilibrium equations are typically applied for each phase (liquid or vapor) individually, but the result can be plotted in a single diagram. In a binary boiling-point diagram, temperature (T ) (or sometimes pressure) is graphed vs. x 1. At any given temperature (or pressure) where both phases are present ...
The pressure on a pressure-temperature diagram (such as the water phase diagram shown above) is the partial pressure of the substance in question. A phase diagram in physical chemistry , engineering , mineralogy , and materials science is a type of chart used to show conditions (pressure, temperature, etc.) at which thermodynamically distinct ...
Mole fraction vs. temperature diagram for a two-component system, showing the bubble point and dew point curves. In thermodynamics, the bubble point is the temperature (at a given pressure) where the first bubble of vapor is formed when heating a liquid consisting of two or more components.

Dutch physicist Johannes Kuenen discovered retrograde condensation and published his findings in April 1892 in his Ph.D. thesis with the title "Metingen betreffende het oppervlak van Van der Waals voor mengsels van koolzuur en chloormethyl" (Measurements on the Van der Waals surface for mixtures of carbonic acid and methyl chloride).
Either, a three dimensional diagram must be drawn, or one variable must be kept constant. It is common to draw ternary phase diagrams at a constant temperature and pressure, in order to be able to draw a two-dimensional diagram. Such a diagram will show how the phases of the system changes with composition at a given temperature and pressure.
Tree diagram; In probability theory, the joint probability distribution is the probability distribution of all possible pairs of outputs of two random variables that ...
