On the basis of a precise formulation of the second law of thermodynamics of Clausius type, the existence of the nonequilibrium absolute temperature and nonequilibrium entropy is proved. These quantities satisfy the Clausius-Planck dissipation inequality for general thermodynamic systems and processes. In this way all main assumptions upon which rational thermodynamics rests are justified in both physical and logical ways. Hence, rational thermodynamics can be regarded as a true thermodynamic image of actual physical phenomena. A non-traditional form of the first law of thermodynamics is expressed in terms of inequalities analogous to those of the second law. Deep logical similarities as well as physical differences between both the laws are thereby revealed.
