Input (English): This quantity can be calculated for water with the Arden Buck equation, which is a recent improvement over the Goff-Gratch equation. Thermogravimetry can be used to calculate this value for solids, and it is related to the molar volume, surface tension, and droplet radius in the Kelvin equation. Another equation relates two values of this quantity to the enthalpy of vaporization and temperature, and is named for Clausius and Clayperon, while this value is modified by mole fractions of species in solution in Raoult's Law. For 10 points, name this measure of a liquid's tendency to evaporate, which, when it exceeds atmospheric pressure, results in boiling.
Output (English): Science
