Correlations of the Characteristic Thermodynamic Parameters of Alkali Metals

Abstract

This work deals with a theoretically and technologically important thermodynamic study on the correlation of the Boyle temperature , the inversion temperature and the acentric factor of cesium, rubidium and potassium. This correlation is established through a generalized van der Waals equation of state. The obtained correlation fits the experimental data for the Boyle temperature , the inversion temperature and the acentric factor of cesium, rubidium and potassium. It has also been established that cesium, rubidium and potassium obey the single-parameter law of corresponding states. It is shown that the ratio of the inversion temperature and the Boyle temperature or the acentric factor can be used as the thermodynamic similarity parameter for cesium, rubidium and potassium.
