One of the original derivations of this equation erroneously calculated a certain term as "three-halves times Boltzmann's constant times particle number," which its author corrected to "five-halves k N" using data on the vapor pressure of mercury.
This equation follows from the conservation laws of an expanding universe filled with a fluid whose pressure is two-thirds its density, as shown by S.H. Pereira. This equation implies that the pre-exponential factor in the Richardson-Dushman equation is a universal constant of thermionic emission. One of the original derivations of this equation erroneously calculated a certain term as "three-halves times Boltzmann's constant times particle number," which its author corrected to "five-halves k N" using data on the vapor pressure of mercury. This equation is valid when volume over the quantity "particle number times thermal wavelength cubed," close quantity, is much greater than one, and it predicts a value of negative infinity at absolute zero. This equation can be derived by calculating the occupied volume in phase space, then assuming that particles are indistinguishable in order to resolve the Gibbs paradox. For 10 points, name this equation that gives the absolute entropy of a monatomic ideal gas.
