Thermodynamics and Energy


VARIAÇÃO DE Entropia e Reversibilidade

Authors: Rodrigo de Abreu

The <> of Thermodynamics is built upon the verification that the increase of energy in a system for a given value of the deformation variable increase the force exerted by the system on the outside. This being the case, the Second Principle is affirmed on the existence of a relation between energy, entropy and deformation variables, a relation which is not postulated but assumed on the basis of the above verification. In this way the Second Principle is established independently of the so called Zero and First Principles.
