• Liquid structure can be considered as a lattice distorted heavily by many dislocation lines. The dislocation density is supposed to be limited by the mutual contact of the cores of the dislocation lines. Calculation of the free energy as function of the dislocation density showed that above a certain temperature the lattice which has no dislocations at low temperatures changes abruptly into liquid by the appearance of the highest density of dislocations. Calculated heat of fusion of various metals agrees fairly well with experiment if the core radius is taken to be of the order of the lattice constant. In this model the thermal expansion of the liquids can be explained just in the same way as that of solids. A method of calculation was applied to determine the Gruneisen constant of molecular liquids with the result confirming this model.
