Measurement of the Compressibility Factor of Gases: A Physical Chemistry Laboratory Experiment

“…7 These experiments are modifications of a method originally developed by Burnett, 8 which is still in use in contemporary research on the nonideality of gases and their mixtures. 9 Our approach to acquiring and analyzing the compressibility data is different from and more direct than that described in refs 4À7, making the experiment simpler for students to understand and carry out. We use a much larger expansion chamber, which allows students to collect their data in a single series of measurements requiring just one evacuation of the apparatus.…”

Third virial coefficients and critical properties of quadrupolar two center Lennard-Jones models

“…Firstly, the improvement of the Burnett technique has allowed to measure third virial coefficients with a precision that was not possible until recently. 16 Secondly, the increase in computer power allows now to determine third virial coefficients numerically in a reasonable amount of time, with error bars similar to or smaller than those attained experimentally. [17][18][19][20] It has also been recently recognized that knowledge of the first few virial coefficients may allow for the development of equations useful in the field of supercritical extraction.…”
