An attempt is made in the article to rigorously axiomatize thermodynamics, i.e., to construct such a presentation of it in which its entire presentation follows from several axioms. At the same time, it turns out that the classical point of view, which consists in the fact that the entire building of thermodynamics can be built on five principles (the so-called minus first, zero, first, second and third laws of thermodynamics), does not stand up to criticism — the number of axioms is much larger. An attempt to reveal the logical necessity of introducing these axioms into the foundations of thermodynamics and revealing their very physical essence (formulation) is undertaken in this article
