  • The gas temperature is 272.98 K, equivalent to -0.17 °C and 31.69 °F.
  • The PV product equals nRT = 2269.6800 J, confirming the gas behaves ideally under these conditions.

Next stepThe ideal gas law assumes no intermolecular forces and zero molecular volume. For accurate results at high pressures or near condensation, use a real-gas model such as the van der Waals or Peng-Robinson equation.
