ON THE FIRST LAW OF TERMODYNAMICS.Entropy is a concept that has long stimulated human curiosity, resulting in an huge intelectual production.The same has not occurred for the first law of thermodynamics, perhaps because of its apparent obviousness.In this article the first law presentation, as displayed in most traditional physical chemistry textbooks, is criticized.An alternative view is suggested, in accordance with temporal thermodynamics.The time derivative local form of the second law is used to stress the entropy concept implications on the notion of internal energy.
