real gas equation

Real gases do not obey ideal gas equation,

The volume of real gases often exceed those calculated by the ideal gas equation. These deviations are best attributed to the:

In the corrections made to the ideal gas equation for real gases, the reduction in pressure due to attractive forces is directly proportional to :

Real gases obey the gas equation : PV=nRT more correctly at low temperature and high pressure.

Under what conditions do the real gases obey more strictly the gas equation, PV = RT ? Explain.

At point P and Q, the real gas deviation with respect to ideal gas is respectively :

The van der Waals' equation for a real gas is:
