Why at low pressures, the real gas behaves as ideal gas?

Answer»

Solution :At LOW PRESSURES, when volume is large, both correction factors in the van der Waals. equations may be neglected.
The equation `(P+(a)/(V^2)) (V - b) = RT,` reduces to PV =RT, ideal gas law.
This is nothing but representing the LIMITING behaviour of gases at infinite small pressures.
