gas | A phase in which molecules are far from each other (a dispersed phase) and the molecules move randomly. Molecules in a gas phase have more translational, vibrational, and rotational energies than liquids or solids at the same temperature and thus have a higher internal energy. | 2A4 | |
gas | diatomic | A gas in which every molecule consists of only two identical atoms. For example: hydrogen, oxygen, nitrogen. | 2A4 |
gas | ideal | 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, 2E2, |

gas | monatomic | A gas in which all of the molecules consist of only one atom. Noble gases like He and Ar are examples of monatomic gases. | 2A4 |
gas | noble | Gases in the right-most column of the periodic table : He, Ne, Ar, Kr Xe Rn. | 2A4 |
gas | real | In principle, all gases are real gases. In practice, gases that deviate from the Ideal Gas EOS by more than 1% are considered to be non-ideal or real gases. | 2E3 |

gauge (gage) pressure | Also known as Gage Pressure. The difference between the absolute pressure and atmospheric pressure. Gauge pressure is what is normally read from a pressure gauge. You must ADD atmospheric pressure to the gauge pressure to obtain the absolute pressure. Gauge pressures CAN be negative ! [ atm, kPa, bar, psig, etc. ] | 1D3 | |
