2. Quantum Statistics of Ideal Fermi-Dirac and Bose-Einstein Gases: a) The second virial B2(T) coefficient in the viral expansion for the pressure for the ideal Fermi and ideal Bose gas both depend on the thermal wavelength. Calculate the thermal wavelength for both an electron gas and helium gas at 4 degrees kelvin and room temperature. b) Explain why the virial coefficient is positive for a Fermi gas and negative for a Bose gas
