First Law of Thermodynamics on the Basis of Plasma Fluid Equations

Abstract

One of the important laws of nature is the first law of thermodynamics, which reflects the principle of Conservation of energy. This law is concerned with ideal frictionless system. Unfortunately Frictional Force plays an important role in many real systems. Thus the ordinary conventional first law of thermodynamics does no longer hold. Thus there is a need to incorporate the effect of friction in this law. Using Plasma equations one succeeded in obtaining a new first thermodynamic law which account for the effect of friction and Potential. This law reduces to the ordinary law in the absence of friction and potential.
