Classic thermodynamics studies and describes the thermal behavior of complex systems, in particular gaseous, reaching the definition of the three principles of thermodynamics and of the concept of entropy. In this paper we want to demonstrate also single charged massive elementary particles have a thermodynamic behavior that is related to the elementary structure and to the electrodynamic mass of particle. Thermodynamics of single elementary particles is defined by physical transformations and by energy exchanges that particles experience when the speed and the temperature change. These transformations allow to define for elementary particles an intrinsic temperature and an intrinsic entropy that have a different behavior with respect to the same physical quantities of complex classic systems and with respect to the collective behavior of particles inside a plasma.
