A residual thermodynamic property is defined as the difference between the property of the real fluid and that of an ideal gas at the same temperature and _pressure, that is

Assuming that a fluid can be described by the viral equation of state with only the second virial coefficient, develop the expressions for the residual contributions to the volume, internal energy and Helmholtz energy at a fixed temperature and pressure.
