It leads to the fact that small liquid droplets (i.e. particles with a high surface curvature) exhibit a higher effective Vapor Pressure , since the surface is larger in comparison to the volume. Another notable example of the Gibbs-Thomson effect is Ostwald Ripening , in which concentration Gradients cause small Precipitates to dissolve and larger ones to grow. The Gibbs-Thomson equation for a precipitate with radius is: : : Atomic volume : : Boltzmann Constant : : Equilibrium partial pressure (or chemical potential or concentration) : : Partial pressure (or chemical potential or concentration) : : Absolute Temperature Ostwald ripening is thought to occur in the formation of Orthoclase Megacrysts in granites as a consequence of Subsolidus growth.
