= Hertz–Knudsen equation
{wiki=Hertz–Knudsen_equation}
The Hertz–Knudsen equation is a fundamental relationship in physical chemistry used to describe the evaporation and condensation of a substance in the context of phase transitions, particularly at the interface between a liquid and vapor or a solid and vapor. The equation provides a way to relate the pressure of a vapor in equilibrium with its liquid phase to the rate of evaporation and the molecular characteristics of the substance.
