When studying gases, Irish chemist Robert Boyle noticed that as he changed the pressure, the volume of a gas would also change. The following data represents what Boyle may have observed: Pressure, 0.100 0.250 0.360 0.420 0.600 0.900 1.10 atm Volume, 3.670 1.402 1.020 0.880 0.615 0.400 0.330 L Inverse, 1/y a. Which is the dependent variable? Explain your answer. b.When plotting pressure and volume, the results do not product a straight line; however, taking the inverse of the dependent variable (inverse = 1/y) gives much more linear data. Use Excel to calculate these inverse values and enter them in the above table. c.Plot the inverse of the dependent variable vs. the independent variable in Excel or a similar spreadsheet program and give the equation of the best-‐fit line and R^2 value.

Question
When studying gases, Irish chemist Robert Boyle noticed that as he changed the pressure, the volume of a gas would also change. The following data represents what Boyle may have observed:
Pressure, 0.100 0.250 0.360 0.420 0.600 0.900 1.10
atm
Volume, 3.670 1.402 1.020 0.880 0.615 0.400 0.330
L
Inverse,
1/y
a.
Which is the dependent variable? Explain your answer.
b.When plotting pressure and volume, the results do not product a straight
line; however, taking the inverse of the dependent variable (inverse = 1/y)
gives much more linear data. Use Excel to calculate these inverse values and enter them in the above table.
c.Plot the inverse of the dependent variable vs. the independent variable in
Excel or a similar spreadsheet program and give the equation of the best-‐fit line and R^2 value.
