Low pressure and high temperature

Vedclass · Answer

(B) gas behaves ideally at low pressure and high temperature. Under these conditions,the intermolecular forces of attraction become negligible,and the volume occupied by the gas molecules becomes negligible compared to the total volume of the gas. Consequently,the van der Waals equation $(p + \frac{an^2}{V^2})(V - nb) = nRT$ reduces to the ideal gas equation $pV = nRT$ because the pressure correction term $\frac{an^2}{V^2} \approx 0$ and the volume correction term $nb \approx 0$.

Under what conditions does a gas behave ideally? Why?
