  From arguments based on Heisenberg's uncertainty principle and Pauli's
exclusion principle, the molar specific heats of degenerate ideal gases at low
temperatures are estimated, giving rise to values consistent with the
Nerst-Planck Principle (third law of Thermodynamics). The Bose-Einstein
condensation phenomenon based on the behavior of specific heat of massive and
non-relativistic boson gases is also presented.
