Kapillärdensättning
Kapillärdensättning, often translated as capillary condensation, is a phenomenon observed in porous materials where vapor condenses in the pores at a relative humidity lower than the bulk saturation vapor pressure. This occurs due to the curved surface of the condensed liquid within the pores, which leads to a lower vapor pressure over the curved interface compared to a flat surface.
The relationship between the pore size, the surface tension of the liquid, and the vapor pressure is
This phenomenon has important implications in various fields. In soil science, it influences the water retention
