Pressure Analysis

The vapor pressure of liquid argon, krypton, and xenon was measured from below the normal boiling temperature to close to the critical temperature. Functional relations were fitted by a multiple regression analysis to the experimental data. Data of other authors are compared directly with the results presented here.Comparison of the vapor pressure curves for the three liquids showed that the classical corresponding states principle was obeyed only poorly and that it was necessary to include quantum corrections in comparing the reduced curves. The adjusted reduction factors agreed reasonably well with those found from vapor pressure analysis by other workers. De Boer plots on the basis of our potential parameters are more linear than those using the parameters of Boato and Casanova.

Specific Heat Jump

In this paper, the superconductor with the competition of superconducting gap and pseudogap in the below crossover temperature region is calculated. The superconducting gap and pseudogap is assumed to arise from independent and competing correlation. The critical temperature, superconducting gap and the specific heat jump are derived in the analytic form and the approximation is used to simplify the equations obtained for the region that crossover temperature and energy of pseudogap are higher than critical temperature. We find that the critical temperature is decreased as the energy of pseudogap and crossover temperature as increased. The superconductor with pseudogap has small specific heat jump in comparison with the BCS value. Increasing the crossover temperature and critical temperature, the specific heat jump is decreased.

This paper presents the results of the measurement of the vapor pressure of vinyl acetate, over the temperature range from 0 °C. to the normal boiling point. The determinations were carried out on vacuum distilled samples with an isoteniscope, differing slightly in detail from that used by Smith and Menzies(7).The normal boiling point is 72.5 °C. The molecular heat of evaporation has been found to be 8211 calories. The equation which represents the results is[Formula: see text]Trouton's constant and the critical temperature have been found to be 23.8 and 228.3 °C.
