The Kelvin Equation describes the relationship between vapor pressure and the curvature of a liquid surface. It is a crucial concept for understanding phase transitions in confined spaces, especially at the nanoscale. The equation is given by: ln(P/P0) = (2γVm)/(rRT) where P is the vapor pressure over a curved surface, P0 is the vapor pressure over a flat surface, γ is the surface tension, Vm is the molar volume, r is the radius of curvature, R is the gas constant, and T is the temperature.
