Question
Why do real gases deviate from the ideal behaviour? What are the conditions under which real gases show ideal behaviour?
✓

Answer

Real gases deviate from the ideal behaviour because gases have sufficient intermolecular forces of attraction and volume occupied by gas molecules cannot be neglected at all conditions of temperature and pressure as assumed by kinetic theory of gases.
At low temperature and high pressure, most of the gases deviate from ideal gas behaviour.
