Two Thermodynamic Laws as the Forth and the Fifth Integral Postulates of Continuum Mechanics
A methodological reduction of the known in physics statements of the first and second laws of thermodynamics to general form of integral postulates adopted in classical mechanics of continuous media, is realized. It is shown that the second law should be represented in the Carathéodory form which makes possible to introduce both absolute temperature and entropy as phenomenological values not having recourse to the model of perfect gas and the Carnot cycle. The local equations being consequences of the integral postulates include mass densities of thermodynamic values which must be defined as scalar or vector fields in material.
