Question
What are real gases?
✓

Answer

Real gases:
  • Gases, which do not obey ideal gas equation under all the conditions of temperature and pressure are called real gases.
  • For real gases, the ratio of PV/RT will be either greater than 1 or less than 1.
  • Real gases show deviation from ideal gas behaviour at higher pressures and lower temperatures.
  • The intermolecular attractive forces are not negligible in real gases.
  • In real gases, the actual volume of the molecules cannot be neglected as compared to the total volume of the container.
