fugacity

fugacity
See fugaciously.

* * *

      a measure of the tendency of a component of a liquid mixture to escape, or vaporize, from the mixture. The composition of the vapour form of the mixture, above the liquid, is not the same as that of the liquid mixture; it is richer in the molecules of that component that has a greater tendency to escape from the liquid phase. The fugacity of a component in a mixture is essentially the pressure that it exerts in the vapour phase when in equilibrium with the liquid mixture.
