Equations of condition and conservation of energy of a simple quasi-equilibrium thermodynamic system are shown to be similar to thermodynamics concepts. Bui the equation of conservation of energy of a simple non-equilibrium system is only a differential expression of the condition equation. A physical nature of entropy is defined. The so called principle of the entropy increase is shown not to be the common law of thermodynamics. A main principle is given of the Nature arrangement as well as the original energy source in the Nature, which is the space-time substance transformation.
