WAYS OF LEARNING OF IDEAL STATE EQUATION (METHODOLOGICAL MATERIAL)

The article presents methods of obtaining the Mendeleev-Clapeyron equation. Thermodynamics considers the macrosystem as a whole and describes its properties not on the basis of the microstructure of the substance, but on the basis of the experiment establishes a connection between the macroscopic parameters of the substance. This method is distinguished by its simplicity, but it has a drawback, which is that its internal mechanism is not explained in the thermodynamic discussion of events. For example, one can experimentally obtain a relationship between the pressure and volume of an ideal gas at constant temperature pV=const, but why this is so can only be explained by the methods of molecular physics.
