Saturated vapor pressure of individual substance. Supplement to interpretations and procedures for processing experimental polythermal data

A universal (that is, actual for any reaction) interconnection between enthalpy (∆ r H ), entropy (∆ r S ), and Gibbs energy (∆ r G ) was applied to the analysis of the formation of saturated vapor of individual condensed (liquid and solid) substances. This allowed us to specify the conceptual and m...

Description
Summary:A universal (that is, actual for any reaction) interconnection between enthalpy (∆ r H ), entropy (∆ r S ), and Gibbs energy (∆ r G ) was applied to the analysis of the formation of saturated vapor of individual condensed (liquid and solid) substances. This allowed us to specify the conceptual and metrological sense of thermodynamic parameters available for estimation within the framework of tensimetric investigations. Proposals for the procedures of experimental data processing were made. The informativity of the approach was illustrated by the example showing the results of processing two arrays of primary data obtained using the static and the flow methods for crystal hafnium(IV) dipivaloylmethanate.
