ABSTRACT: It has been shown that the first
principle of thermodynamics follows from the conservation laws for energy and
linear momentum. And the second principle of thermodynamics follows from the
first principle of thermodynamics under realization of the integrating factor
(namely, temperature) and is a conservation law. The significance of
the first principle of thermodynamics consists in the fact that it specifies
the thermodynamic system state, which depends on interaction between conservation
laws and is non-equilibrium due to a non-commutativity of conservation laws.
The realization of the second principle of thermodynamics points to a
transition of the thermodynamic system state into a locally-equilibrium state. Phase transitions are examples of such transitions.
