The constitutive relation between thermophysical properties, temperature and hydrostatic pressure of liquid materials is studied on the basis of the first author's inelastic deformation theory (combined deformation mechanism model). We consider, in this paper, that the structure of a material changes simultaneously when the deformation mechanism or the constitutive relation changes at some temperature and hydrostatic pressure. An examination of experimental data by this concept lead to the following conclusions : the constitutive relation for each thermal property at the liquid region is divided into subregions bounded by the broken points : the constitutive relations of water for viscosity, thermal conductivity and saturation pressure are well explained, quantitatively by the proposed equations which are of the same type as derived from Arrehnius equation : the temperature at which the isobaric specific heat capacity is maximum seems to be the boundary between liquid and gas.
