Two tanks which contain water are connected to each other through a valve. The initial conditions are as shown (at equilibrium):
The constant of vander Waal's equation can be related to the coefficients of the virial equation. Vander Waal's equation provides a good overall description of the real gas PVT behaviour. Now let us
