Ideal gas kinetic theory

The distribution modulus, 9 of the canonical ensemble thus possesses the property of an empirical temperature 9 = kT. The proportionality constant, by analogy with ideal gas kinetic theory, is the same as Boltzmann s constant. 

Compressibility and noncontinuum effects are related. For an ideal gas, kinetic theory leads to the relationship (Sll) ...

By contrast it may be helpful to re-examine the consensus model in which the universe is considered made up of galaxies which interact like gas molecules in a situation of zero pressure. By simple ideal-gas kinetic theory the kinetic energy, given by the product pV, and the temperature, T = pV/R must both be zero in such a sample. There is no further argument about this - the distance between a pair of such galaxies must remain constant, unless the measuring scale is shrinking, which means that space expands.
