PROCESSING THE DATA (PART 2)
1. With the best-fit curve still displayed, choose Interpolate from the Analyze menu. A vertical cursor now appears on the graph. The cursor’s volume and pressure coordinates are displayed in the floating box. Move the cursor along the regression line until the volume value is 5.0 ml (or any lowest readable point on the graph). Note the corresponding pressure value. Now move the cursor until the volume value is doubled (10.0 ml). What does your data show happens to the pressure when the volume is doubled?
