Under what conditions of temperature and pressure do you think that the gas laws would work best? Please be specific

  • chemisrty -

    Since the ideal gas law neglects both molecular size and intermolecular attractions, the ideal gas law is most accurate for monoatomic gases at high temperatures and low pressures. The neglect of molecular size becomes less important for larger volumes, i.e., for lower pressures. The relative importance of intermolecular attractions diminishes with increasing thermal kinetic energy i.e., with increasing temperatures.
