b. When the pressure reading has stabilized, click Keep. (The person holding the
syringe can relax after Keep is clicked.) Type in the total gas volume (in this
case, 5.8 mL) in the edit box. Remember, you are adding 0.8 mL to the volume of
the syringe for the total volume. Press OK to keep this data pair.
c. Move the piston to the 7.0 mL line. When the pressure reading has stabilized,
click O Keep and type in the total volume, 7.8 mL.
d. Continue this procedure for syringe volumes of 9.0, 11.0, 13.0, 15.0, 17.0, and
19.0 ml.
e. Click Stop when you have finished collecting data.
5. When the data collection is complete, a graph of pressure vs. volume will be
displayed. To examine the data pairs, tap any data point. In your data table, record
the pressure and volume data pairs displayed for each data point.

6. Examine the graph of pressure vs. volume. Based on this graph, decide what kind of
mathematical relationship you think exists between these two varíables, direct or
inverse. To see if you made the right choice:
a. Choose curve fit from the Analyze menu.
b. Select Power as the Fit Equation. The curve fit statistics are displayed in the form
of y = Ax^B, where x is the volume, y is the pressure, A is a proportionality
constant, and B is the power of x. If the relationship is direct, then B is very close
to +1; if inverse, B is very close to -1.
