A system of equations of heat and mass transfer, phase transformations, and deformation of porous bodies in sorption and desorption are derived and substantiated. Formulas for the area of contact between a liquid and gas in a unit volume of a porous body, for the intensity of phase transition, heat of phase transformations, equilibrium partial vapor pressure, and for the thickness of adsorbate layer on the surfaces of capillaries with allowance for the influence of adsorption forces are presented. The results of a comparison between calculated and experimental data are given.
