4. Ebullioscopic constant - Wikipedia

   en.wikipedia.org/wiki/Ebullioscopic_constant

   A formula to compute the ebullioscopic constant is: [2] = R is the ideal gas constant. M is the molar mass of the solvent. T b is boiling point of the pure solvent in kelvin. ΔH vap is the molar enthalpy of vaporization of the solvent.

5. Boiling point - Wikipedia

   en.wikipedia.org/wiki/Boiling_point

   Water boiling at 99.3 °C (210.8 °F) at 215 m (705 ft) elevation. The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid [1] [2] and the liquid changes into a vapor.

7. Trouton's rule - Wikipedia

   en.wikipedia.org/wiki/Trouton's_rule

   Enthalpies of melting and boiling for pure elements versus temperatures of transition, demonstrating Trouton's rule. In thermodynamics, Trouton's rule states that the (molar) entropy of vaporization is almost the same value, about 10.5 in nondimesnional units, or 85–88 if expressed in units J/(K·mol), for various kinds of liquids at their boiling points. [1]

8. Zeotropic mixture - Wikipedia

   en.wikipedia.org/wiki/Zeotropic_mixture

   Different zeotropic mixtures have different temperature glides. For example, zeotropic mixture R152a/R245fa has a higher temperature glide than R21/R245fa. [7] A larger gap between the boiling points creates a larger temperature glide between the boiling curve and dew curve at a given mass fraction. [4]

9. Critical point (thermodynamics) - Wikipedia

   en.wikipedia.org/wiki/Critical_point...

   The commonly known phases solid, liquid and vapor are separated by phase boundaries, i.e. pressure–temperature combinations where two phases can coexist. At the triple point, all three phases can coexist. However, the liquid–vapor boundary terminates in an endpoint at some critical temperature T c and critical pressure p c. This is the ...
