PHYS-4420 THERMODYNAMICS & STATISTICAL MECHANICS SPRING 2006 Class Activity - Class 26 April 25, 2006 Name_________SOLUTION__________________ At the center of the sun, the temperature is approximately 107 K and the concentration of electrons is approximately 1032 per cubic meter. Would it be (approximately) valid to treat these electrons as a “classical” ideal gas (using Boltzmann statistics), or as a degenerate Fermi gas (with T  0), or neither. (Circle the correct answer, and show why you chose it.)
