The behaviour of real gas approaches ideal behaviour at

Step-by-step solution

The equation of state for a real gas is given by the van der Waals equation: (P + an^2 V^2 )(V - nb) = nRT . For a real gas to approach ideal gas behaviour, the intermolecular forces of attraction must be negligible and the volume occupied by the gas molecules must be negligible compared to the total volume of the container. The term an^2 V^2 becomes negligible when the pressure P is very low, as the volume V becomes very large. Similarly, the term nb becomes negligible compared to V at low pressures and high tempe
