Thermodynamic Properties of Oxygen

Temperature Pressure Density Volume Int. energy Enthalpy Entropy C, CF Sound speed Joule-Thomson Therm, cond. Viscosity 

The uncertainties of the equation of state are 0.1% in density, 2% in heat capacity, and 1% in the speed of sound, except in the critical region. For viscosity, the uncertainty is 1% in the dilute gas at temperatures above 200 K, and 5% in the dilute gas at lower temperatures. The uncertainty is around 2% between 270 and 300 K, and increases to 5% outside of this region. The uncertainty may be higher in the liquid near the triple point. The uncertainty for the dilute gas is 2% with increasing uncertainties near the triple point. For thermal conductivity, the uncertainties range from 3% between 270 and 300 K to 5% elsewhere. The uncertainties above 100 MPa are not known due to a lack of experimental data.

This semi-empirical method is recommended as a convenient and economic alternative to determine ideal gas thermodynamic properties of oxygenated heterocycles. 

Use the information in Illustration 6.4-1 and the Soave-Redlich-Kwong equation of state to compute the thermodynamic properties of oxygen along the following two isotherms ... 

Of course, using an equation of state, not only can the vapor pressure of a fluid be calculated, but so can other thermodynamic properties along the vapor-liquid phase boundary. This is demonstrated in the following illustration, which is a continuation of Dlustration 6.4-1, dealing with the thermodynamic properties of oxygen.

Thermodynamic Properties. Ordinary water contains three isotopes of hydrogen [1333-74-0] (qv), ie, H, H, and H, and three of oxygen [7782 4-7] (qv), ie, O, and The bulk of water is composed of and O. Tritium [15086-10-9] H, and are present only in extremely minute concentrations, but there is about 200-ppm deuterium [16873-17-9], H, and 1000-ppm in water and steam (see Deuterium and tritium). The thermodynamic properties of heavy water are subtly different from those of ordinary water. lAPWS has special formulations for heavy water. The properties given herein are for ordinary water having the usual mix of isotopes.

Fei O, called wiistite, has been studied from the viewpoints of thermodynamics and physicochemical properties. As mentioned in Section 1.1, stoichiometric FeO cannot be prepared under the usual conditions. Many investigators have studied the thermodynamic properties of wustite by use of various kinds of techniques. Here we introduce a study carried out by Fender and Rileywho used a solid electrolyte cell (see Section 1.4.8) to determine the equilibrium oxygen pressure Por The following cell was utilized,... 

Matrix isolation methods of synthesis have also been used to prepare and study coordination compounds. These involve the vaporization of a metal and a potential ligand, which are then rapidly carried in a stream of inert gas to a very cold surface, where the compound which has been formed is quickly trapped in the solid matrix. It is possible to determine the type of bonding, the structure and the thermodynamic properties of the compounds formed. Only small ligand molecules have been used thus far carbon monoxide, nitric oxide, nitrogen and oxygen, for example, but molecules of great interest have been formed. Some such are [Pd(C2H4)], [Pd(N2)3], [Ni(N2)202], [Ni(N2)4] and [Ni(CO)(N2)3].41...
