Energy Conservation Principle from the Perspective of the Energy Structure Theory

In this paper, the energy conservation principle is investigated from the perspective of the energy structure theory. Energy structure theory presents the basic equation as energy structure equation has been developed to study physical processes considering effects of the second law of thermodynamics directly. Energy components are used as basis of the energy structure equation. In this paper, to investigate the energy conservation principle using the energy structure equation, the variation of the energy structure equation is studied in different paths for the same amount energy applying to the system. In fact, a quasi-static path is used as a reference path, and other paths are studied using this reference when the same amount of energy is applied to the system in different conditions. Using this approach, in fact, energy conservation principle is applied to the energy structure equation, and therefore, the resultant relation has the first and second laws of thermodynamics as its basis together that has been developed in one relation. Therefore, the extracted relation will be a bidirectional relation that means all processes must satisfy this relation and vice versa.
