Third Virial Coefficient for Air-Water Vapor Mixtures*
The third interaction virial coefficient Caww for a ir-water vapor mixtures is estimated in the temperature range 0 to 100 °C, by means of an approximate method based on molec ular assoc iation . The res ult s are believed accurate to within a fac tor of two. The value of CawlV can be combined with prev ious es timates of the other interaction coefficient C",m and the values of the third virial...
متن کاملFirst-Principles Calculation of the Third Virial Coefficient of Helium
Knowledge of the pair and three-body potential-energy surfaces of helium is now sufficient to allow calculation of the third density virial coefficient, C(T), with significantly smaller uncertainty than that of existing experimental data. In this work, we employ the best available pair and three-body potentials for helium and calculate C(T) with path-integral Monte Carlo (PIMC) calculations sup...

متن کاملTheoretical study of intermolecular potential energy and second virial coefficient in the mixtures of CH4 and H2CO gases
To get a mole of a gas, it is necessary to calculate the intermolecular interaction. Theseintermolecular interactions can be depicted by drawing the potential energy of a pair molecule inrelation to the distance. The intermolecular potential energy surface in the mixtures of CH4-H2COgases from ab initio calculations has been explored. In ab initio calculations the basis setsuperposition error (...
متن کاملImproved First-Principles Calculation of the Third Virial Coefficient of Helium
We employ state-of-the-art pair and three-body potentials with path-integral Monte Carlo (PIMC) methods to calculate the third density virial coefficient C(T) for helium. The uncertainties are much smaller than those of the best experimental results, and approximately one-fourth the uncertainty of our previous work. We have extended our results in temperature down to 2.6 K, incorporating the ef...
