Homework Help: Maxwell-Boltzmann speed distribution

  1. May 15, 2006 #1
    Does the Maxwell-Boltzmann speed distribution hold for all ideal gases or just for the mono-atomic ones? If it holds for all gases, why? What happens with the degrees of freedom, don't they change things?? I'm very confused.

    It certainly doensn't hold for all gases. The Maxwell-Boltzmann distribution only holds when quantum effects are negligible. When that condition is not satisfied then the difference between bosons and fermions must be taken into account. Hence, the Bose-Einstein and Fermi-Dirac distributions.

    Does it hold for all ideal gases, even if they are not mono-atomic?
