En thermodynamique, on appelle entropie une grandeur caractéristique des corps qui dépend de leur état physique et qui est une fonction d'état. Elle ne peut être mesurée directement, parce qu'elle a été conçue pour donner une évaluation de la capacité d'un corps ou d'un système à évoluer vers un état d'équilibre. Les transformations d'un système peuvent s'effectuer, suivant les contraintes imposées, par des variations soit positives, soit négatives de l'énergie interne E, de l'enthalpie H, de l'énergie libre F, de l'enthalpie libre G, alors qu'un état d'équilibre est déterminé par l'annulation de ces variations. 3, record 5, French, - entropie
