Among the following, the incorrect statement is :

At low pressure, real gases show ideal behaviour.

At very low temperature, real gases show ideal behaviour.

At very large volume, real gases show ideal behaviour.

At Boyle's temperature, real gases show ideal behaviour.

Answer and worked solution

Official answer: B

Real gases approach ideal behaviour at low pressure, high temperature and large volume. At very low temperature intermolecular attractions dominate, so (2) is incorrect.

Topics:Real gases and van der Waals equation
