H2O gas

### Information

Notes:

- The radius of H2O is 282 pm (http://www.lsbu.ac.uk/water/molecule.html). Using the radius of H from http://en.wikipedia.org/wiki/Hydrogen and the center-to-center distance of hydrogen atoms in H2O from [Avogadro], 156.6 pm, the radius of H2O would be (120 + 156.6/2) pm = 198.3 pm.
- The virial coefficients are from [Dymond2002, p. 4]. The temperature range of the coefficients is [350, 770] K, but this is not enforced in the functions.
