“…The deviations of second virial coefficient, B(T), calculated by eq 8 from the calculations of Hellmann et al 37 were in the range from −0.8 to 2.4 cm 3 •mol −1 in the experimental temperature range from 308 to 370 K. However, the deviations became a little larger for the temperature lower than 300 K. The second virial coefficient data of Hurly et al 8 was much closer to calculations of Hellmann et al 37 than the calculations of eq 8 because their results were from the combination of the speed of sound and pvT measurements and the wider experimental temperature range. However, the calculation from the EoS of Kaplun et al 38 showed much higher deviations that has exceeded 10 cm 3 •mol −1 , especially at the temperature lower than 300 K.…”

“…Figure 6 compares the B(T) from eq 8 with the calculations of quantum mechanics by Hellmann et al, 37 the calculations of Helmholtz energy EoSs developed by Lemmon and Span 33 and Kaplun et al, 38 and the general virial coefficient correlation developed by Meng et al 39 The experimental values of the a Expanded uncertainty is at the confidence level of 0.95. second virial coefficient of xenon in literatures in the past 70 years were also shown in Figure 6 for comparison. The deviations on the basis of the calculations of quantum mechanics by Hellmann et al 37 were shown in Figure 6b.…”

Measurement of high-pressure xenon gas absorption in acrylic

“…B is the second density virial coefficient. We take the value B = 0.00103 [L/g] (at 300 K) from semi-empirical models [18] based on experimental data of gaseous xenon in a broad range of pressures [19]. Such nonlinear term leads to a 6% deviation on pressure at 10 bar from the idea gas model result, and it is in good agreement with the data.…”
