The Ostwald—Freundlich equation governs boundaries between two phases ; specifically, it relates the surface tension of the boundary to its curvaturethe ambient temperature, and the vapor pressure or chemical potential in the two phases.

One consequence of this relation is that small liquid droplets i.

Another notable example of this relation is Ostwald ripeningin which surface tension causes small precipitates to dissolve and larger ones to grow. Ostwald ripening is thought to occur in the formation of orthoclase megacrysts in granites as a consequence of subsolidus growth.

InEcuacon Kelvin William Thomson obtained the following relation governing a liquid-vapor interface: In his dissertation ofRobert von Helmholtz son of the German physicist Hermann von Helmholtz derived the Ostwald—Freundlich equation and showed that Kelvin’s equation could be transformed into the Ostwald—Freundlich equation.

According to Lord Kelvin’s equation of[6] [7]. Assuming that the vapor obeys the ideal gas lawthen.
