Plot pressure against volume for 1 mol of

(a) Ideal gas molecules,

(b) Carbon dioxide molecules,

(c) Ammonia molecules, and

(d) Benzene molecules for the range V = 0.1 L to 1.0 L at 375 K. Use the van der Waals equation to determine the pressures of the real gases. Use a spreadsheet or the graphical plotter on the Web site for this book. Compare the shapes of the curves and explain the differences.
