Ideal gasses have a value of 1 for this parameter. For 10 points each:
[10m] Name this parameter denoted Z. This parameter measures how a gas deviates from the ideal gas law and can be computed using virial equations of state.
ANSWER: compressibility factor [or compression factor]
[10e] Equations of state describe the thermodynamic relationship between this quantity, temperature, and volume. This quantity’s SI unit is the Pascal.
ANSWER: pressure [prompt on P]
[10h] This principle, proposed by van der Waals, states that all fluids at the same reduced temperature and pressure will have a similar compressibility factor.
ANSWER: theorem of corresponding states [accept principle or law in place of “theorem”]
