Abstract:  On the basis of analysis of the adsorption and desorption equilibria of water vapour on active carbon the existence of an undercooled adsorbed phase up to the temperature of — 30°C was found. The limit of stability of adsorbed water vapour was determined by the application of the thermodynamic condition and was compared with the limit of stability of liquid phase. The experimentally determined limit of stability of the adsorbed phase did not comply with the calculated limit of stability of the liquid phase, nevertheless it showed an analogous temperature dependence.
