Which gas under the specified conditions would come closest to exhibiting ideal gas behavior?

Question

Quizplus · Accepted Answer

Ideal gas behavior is most closely approached at low pressure and high temperature, which minimizes interactions between gas molecules. H₂O (water vapor) under these conditions would behave more ideally than NH₃ (ammonia) because water vapor is a smaller molecule with less polar interactions compared to ammonia.
