Hard and Soft - Core Equations of State for Simple Fluids: VI. General Theory of Termination Temperatures,and a Validity Criterion for the Second Virial Coefficient |
| |
Abstract: | Abstract A general proof is given that the classical second virial coefficient satisfies the requirement for the non-existence of a termination point of any locus of Cv extrema. This validity criterion is applied to some proposed forms for the second virial coefficient. The order of the termination temperatures is verified for a fairly general intermolecular potential. In particular a proof is given that TF lies between TC and TA. Also the hard-core limit of the ratio TD/TA(~2) is examined briefly. |
