The Equilibrium State

  • J. A. Bittencourt


The equilibrium distribution function is the time-independent solution of the Boltzmann equation in the absence of external forces. In the equilibrium state the particle interactions do not cause any change in the distribution function with time and there are no spatial gradients in the particle number density. We deduce in this section an expression for the equilibrium distribution function, known as the Maxwell-Boltzmann or Maxwellian velocity distribution function.
