Hard-spheres Gas
The first three virial coefficients for hard spheres can be determined analytically
-
= = =
Higher-order ones can be determined numerically using Monte Carlo integration. We list
-
= = =
A table of virial coefficients for up to eight dimensions can be found on the page Hard sphere: virial coefficients.
The hard sphere system exhibits a fluid-solid phase transition between the volume fractions of freezing and melting . The pressure diverges at random close packing for the metastable liquid branch and at close packing for the stable solid branch.

Famous quotes containing the word gas:
“... when I awake in the middle of the night, since I knew not where I was, I did not even know at first who I was; I only had in the first simplicity the feeling of existing as it must quiver in an animal.... I spent one second above the centuries of civilization, and the confused glimpse of the gas lamps, then of the shirts with turned-down collars, recomposed, little by little, the original lines of my self.”
—Marcel Proust (1871–1922)
