A dynamic equation of state at the solid-liquid interface for a lipuid-saturated "solid-liquid-porous media" system has been derived from a thermodynamic study modeling simultaneous heat and mass transfer through purous media from the liquid supply front to the solid-liquid interface. This is the first step in building a mathematical model which macroscopically describes a freezing expansion phenomenon with mass transfer in saturated porous media. It has been revealed that the derived dynamic equation of state generalizes the so-called generalized Clausius-Clapeyron equation, i.e.the static equation of state for porous media without mass transfer, and that mechanical energy produced at the solid-liquid interface is equal to mechanical energy dissipation due to the mass transfer.
