ideal critical molar volume | The molar volume at of a pure substance predicted by the Ideal Gas EOS at the critical temperature and pressure of that substance. [ L/mol ] | 2E8 | |
ideal gas | A gas that obeys the ideal-gas equation of state. All real gases approach ideality at low pressures and high temperatures. For most gases, less than 1% error is incurred by treating them as ideal gases as long as the molar volume is greater than 20 L/mole. Diatomic gases and most noble gases can be treated as ideal gases as long as their molar volume exceeds 5 L/mole. | 2D2 | |

intensive property | Properties of a system that are independent of the size of the system. This means that if you could magically divide the system into two equal subsystems and then measure the value of the property in one of the subsystems, the value that you measured would be the same as the value of that property in the original system. Temperature, pressure, molar volume and molar enthalpy are examples of intensive properties. | 3C4, 3D1, 7B3 | |
