Thermodynamics and Energy


Specific Entropy of Physical Systems

Authors: Daniele Sasso

The concept of entropy is generally defined for systems in which there is a heat exchange and it is connected with concepts of temperature and of internal disorder of system. This paper has the aim of examining the possibility of extending entropy to the generality of physical systems through the concept of specific entropy in which not necessarily heat is the only shape of energy that has to be considered. The outcome is that the concept of entropy can be extended from thermodynamic systems to other physical systems, including mechanical, gravitational and elementary electrodynamic systems. While all physical systems show the same behaviour with respect to the specific entropy, only mass electrodynamic particles show a different behaviour in instability conditions.
