Vapor pressure methods: A source of experimental thermodynamic data

Abstract

An overview is given of the vapor pressure methods which are used for the determination of partial thermodynamic quantities. The methods are divided into four groups: static methods (pressure gauges, atomic absorption, and others); dynamic methods (boiling point method, transpiration method); effusion methods (Langmuir method, different variants of the Knudsen method); equilibration methods (equilibration with gas mixtures, isopiestic method, dew point method). The characteristics of each group are discussed shortly, and some examples of application are given from the recent literature.

Vapor Pressure of Explosives: A Critical Review

“…A large number of techniques for measuring vapor pressures have been suggested and used. Reviews of vapor pressure measurement methods are given by Ipser [16] and Delle Site [17]. Vapor pressure measurements on explosives have been done with a variety of methods (see references in Table 1).…”

Thermodynamics of liquid alloys

“…[1][2][3][4][5][6][7][8][9][10]. Calorimetric measurements to determine the enthalpy of formation and the heat capacity of liquid alloys are discussed in Section 2.…”

Thermodynamic properties of liquid Au–Cu–Sn alloys determined from electromotive force measurements

“…Knott et al [6] used calorimetric measurements to determine the integral enthalpy of mixing of Au–Cu–Sn system. However, measurements were performed at constant 1273 K and the Gibbs energies cannot be obtained, so it is necessary to employ other experimental methods, such as vapour pressure measurements or electromotive force (EMF) measurements, for the determination of a complete thermodynamic description [7,8] . Recently, an EMF method with solid electrolyte was carried out by Wierzbicka-Miernik et al [9] in the temperature range from 900 to 1360 K, to study the thermodynamic data of this system.…”
