3. complete the following for liquid water at t = 373.15 k: a. plot f l versus p, using the peng robinson equation of state to calculate all values of f l . b. plot f l versus p, using the poynting method to calculate all values of fl . explain and justify your approach for determining fsat for thiscalculation. c. re-do parts a and b for liquid water at t = 473.15 k. discuss any differences in your approach for the two temperatures.

Answerhund's rule;

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
