Abstract:
Measurements of (∂P/∂T)V of carbon tetrachloride at ten different temperatures between —7° and 70°C yield an equation for the internal pressure (∂E/∂V)T=3346[1—2.97×10—3(t—25)—12.6×10—6(t—25)2] atmospheres. Comparison with the cohesive energy density (ΔEv/V) confirms previous observations (Hildebrand and co-workers) that the ratio of the internal pressure to the cohesive energy density is approximately unity and further shows this ratio to be remarkably constant over the entire 77° range of temperature. The experimental data on the internal pressure are in marked disagreement with the predictions of ``free-volume theory'' (Lennard-Jones and Devonshire, Hirschfelder and co-workers).
