| Oct 20, 2016 at 22:49 | comment | added | user26143 | Simple mathematical expressions reflect the underlying mathematical forms of the physical equations are simple. However, the underlying physical theory, namely quantum theory, is not simple :( Hence, we would naturally expect the exact solution (presumably it exists), even its accurate approximation, not to be simple... | |

| Nov 12, 2012 at 23:56 | comment | added | matt_black | Mathematically we can't even solve the gravitational 3-body problem in general with a closed form solution. And that has simpler forces (well, gravity, with a neat inverse-square law) than those that act between molecules in a gas. So that's not very hopeful. | |

Much better without sacrificing the basic cubic equation structure is the Soave-Redlich-Kwong or Peng-Robinson EOSs. | |
| May 13, 2012 at 14:48 | comment | added | user95 | Even if you restrict yourself to a cubic equation of state, you can certainly do better than van der Waals. Some tests I did a few years back point to the Redlich-Kwong equation being one of the best two-parameter equations of state for a good range of pressures and temperatures. Of course, if you need to do better than that, you use virial... | |
