Abstract
The state of water adsorbed on active carbons and canal soot was studi ed using the ''chemical potential-entropy-temperature'' diagram. In th e range of the relative pressures from 0.174 to 1, the state of adsorb ed water is similar to the state of a stretched liquid. The molar volu me, heat of evaporation, and surface tension of stretched water were c alculated at different relative pressures. Near the spinodal, the mola r volume of stretched water is 25% higher, and the surface tension is considerably fewer compared to water.
