WebMar 15, 2024 · The compressibility factor (Z) is a useful thermodynamic property for modifying the ideal gas law to account for behavior of real gases. It is a measure of how much the thermodynamic properties of a … WebSummary In this experiment, pressure data was gathered for helium and carbon dioxide gas to evaluate the deviations from ideal gas behavior. The experimental data was used to calculate the compressibility factor, the second and third virial coefficients, and the fugacity for both gases. The compressibility factor describes the deviation of a real gas …
