Resumen de Multivariable Model Fitting as Applied to Air, a Physical Chemistry Experiment
Jonathan P. Antle, Jerry T. Godbout, Scott Simpson
Students in an upper-level physical chemistry course utilized an open-sourced statistical software package to construct models fitted to experimental pressure–volume data. In the first part of the experiment, students familiarize themselves with model fitting. In the second part of the experiment, students determine which truncated version of the virial equation of state is statistically valid to properly model air. This experiment demonstrates proper multivariable linear regression model construction, along with the nonideality of air.
