(a) The ideal gas law in terms of pressure (P), particle density (n), and average kinetic energy per particle (K.avg) is given by the equation: PV = nK.avg. (b) If the electrons in a white dwarf behave quantum mechanically according to the de Broglie relation, their maximum wavelength () can be determined. The de Broglie relation states that = h/p, where h is Planck's constant and p is the momentum. In this case, the maximum wavelength of the electrons in a white dwarf is approximately _ma
