Question
A gas that follows Boyle’s law, Charle’s law and Avogadro’s law is called an ideal gas. Under what conditions a real gas would behave ideally?
✓

Answer

At high temperature and low pressure, the gases behave ideally since the two postulates of kinetic theory of gases are true under these conditions.
  1. The volume of a molecule of a gas is negligible as compared to its complete volume.
  2. There is negligible force of attraction between the molecules of a gas.
