In 1982, IUPAC (“eye-you-pack”) amended its definition of this state to use metric instead of imperial units. For 10 points each:
[10m] Name this reference state which is now defined to occur at 273.15 Kelvin and one bar. Consequently, a mole of ideal gas at this state now has a volume of 22.7 liters, not 22.4.
ANSWER: standard temperature and pressure [or STP; reject “thermodynamic standard state”]
[10e] On the Celsius scale, STP occurs at this temperature, the freezing point of water.
ANSWER: zero degrees Celsius [or 0 degrees centigrade]
[10h] The second of these quantities is a good estimate for the difference in molar volume between a real gas and an ideal gas at STP. These quantities are symbolized capital B and multiply powers of volume in a non-ideal gas law.
ANSWER: virial coefficients [or coefficients of the virial equation equation of state; prompt on coefficients; prompt on virial law or virial equation of state or virial]
