Gases (Chemistry)

Recall cards on the behavior of gases: gas pressure (its definition as force per area, its origin in molecular collisions, the pascal, atmosphere, torr, mm Hg, bar, and psi units and their conversions, barometers and manometers, and hydrostatic pressure); the simple gas laws (Amontons's/Gay-Lussac's, Charles's, Boyle's, and Avogadro's laws with their equations) and the ideal gas law PV = nRT with the gas constant, standard temperature and pressure, the standard molar volume, the combined gas law, and absolute zero; gas stoichiometry (gas density and molar mass from the ideal gas law, the law of combining volumes, Dalton's law of partial pressures, mole fraction, and collecting a gas over water); effusion and diffusion (mean free path, Graham's law, and uranium enrichment); the kinetic-molecular theory (its postulates, molecular kinetic energy, root-mean-square speed, and the Maxwell-Boltzmann distribution); and non-ideal gas behavior (deviations at high pressure and low temperature, the compressibility factor, and the van der Waals equation).
