==Abstract==

Previously, we established a connection between the macroscopic classical laws of gases and the quantum mechanical description of molecules of an ideal gas (T. Yarman et al. arXiv:0805.4494). In such a gas, the motion of each molecule can be considered independently on all other molecules, and thus the macroscopic parameters of the ideal gas, like pressure ''P'' and temperature ''T'', can be introduced as a result of simple averaging over all individual motions of the molecules. It was shown that for an ideal gas enclosed in a macroscopic cubic box of volume ''V'', the ''constant,'' arising along with the ''classical law of adiabatic expansion,'' i.e. ''PV<sup>5/3</sup> = constant'', can be explicitly derived based on quantum mechanics, so that the instant comes to be proportional to ''h<sup>2</sup>/m'' here ''h'' is the Planck Constant, and ''m'' is the relativistic mass of the molecule the gas is made of. In this article we show that the same holds for a photon gas, although the related setup is quite different than the previous ideal gas setup. At any rate, we come out with ''PV<sup>5/3</sup> ~ hc = constant'', where ''c'' is the speed of light. No matter what the dimensions of the ''constants'' in question are different from each other, they are still rooted to universal constants, more specifically to ''h<sup>2</sup>'' and to ''hc'', respectively; their ratio, i.e. ''V<sup>1/3</sup> ~ h/mc,'' interestingly pointing to the ''de Broglie relationships'' cast.
