| Abstract |
Thermodynamic entropy and four different functions used to describe it within mechanical
models are considered. It is shown that all four variants have properties that differ significantly from
the properties of entropy introduced in thermodynamics based on experimental data. It is established
that, in order to comply with the approaches used in thermodynamics, the widely used mechanical
model of a rarefied gas should consider almost exclusively processes that assume the presence of external forces acting on the system. It is noted that such a requirement allows a new approach to the use of
mechanical models for studying irreversible physical phenomena. |
