Using data from the steam tables, make isotherm plots of P-V for both liquid water and steam at the temperatures T = 100, 200, 300, and 400°C. Then, make plots of P-V , at the same temperatures and over the same range of values of V , using the Peng- Robinson, Soave, and van der Waals equations. Comment on the accuracies of the equations of state and on the different features shown in the plots at the five different temperatures.
