The “equation of state” of a fluid at thermal equilibrium is the relation that links, for a given particle number N, its pressure P, volume V, and temperature T = 1/kBβ. We have just studied the variations of the total particle number. We shall now examine the pressure of a fermion or boson ideal gas.
