Question
A graduate student wants to use van der Waals' equation to express the pressure-volume-
temperature relations for a gas. Her project requires a reasonable degree of precision in
the p-V-T calculations. Therefore, she made the following experimental measurements with
her setup to get an idea of how easy the experiment would be:
Temperature, K
Pressure, atm
Volume, ft'/lb mol
273.1
273.1
200
1.860
1000
0.741
Determine values of constants a and b to be used in van der Waals' equation that best fit
the experimental data.
