Van Der Waals equation of state

英语百科

Van der Waals equation

van der Waals isotherms. The model correctly predicts a mostly incompressible liquid phase, but the 
oscillations in the phase transition zone do not fit experimental data.
van der Waals isotherms and oscillations, temperatures, T, below and above TC. Shown in this PV diagram are a series of 5 isotherms for temperatures ranging from below (blue) to above (red) TC, where the upward arise and downward dip in the isotherm predicted by the van der Waals equation (the
van der Waals isotherm oscillation and Maxwell's equal areas.[13] Maxwell's rule eliminates the oscillating behavior of the isotherm in the phase transition zone by defining it as a certain isobar in that zone. The above isotherm is for a reduced temperature of  TR=0.9. The Maxwell correction is at a vapor pressure of pV≈0.64700 between the reduced volume of the pure liquid VL≈0.60340 and the pure gas VG≈2.3488 at the vapor pressure.
