Sobre a primeira lei da termodinâmica: as diferenciais do calor e do trabalho On the first law of thermodynamics: heat and work differentials

By Joaquim Anacleto and Alcinda Anacleto


<abstract language="eng">We treat some subtleties concerning the First Law of Thermodynamics and discuss the inherent difficulties, namely the interpretation of the heat and the work differentials. By proposing a new differential equation for the First Law, which is written using both system and neighborhood variables, we overcome the mentioned difficulties and establish a criterion for the definition of heat and work
