Roulette Theory Applied to Liquid Metals |
| Abstract |
Roulette theory has been applied to liquid metals to calculate the thermodynamic properties of Na, Ag, Cu, K, Au, Pb, Cs, Hg and Rb. The partition function was formulated under the assumption that molecules of the liquid state consist of Einstein molecules, Lennard-Jones and Devonshire molecules, and van der Waals molecules. Although a liquid metal is known a severe test for any liquid theory to lead to large differences between observed and. calculated values for thermodynamic properties, the agreement is quite good for molar volume and vapor pressures for many liquid metals. The results concerning Cv, Cp, and β are not in as good agreement as might be hoped, but it is clear that the theory is correct in principle even for liquid metals. |
