Determination of the proportional relationship between gas volume and gas pressure
Assuming a fixed quantity of a gas at a constant temperature, a decrease in the volume should result in…..
Keeping temperature and number of moles of gas constant.
Vary the volume of air in a closed container and measure the resulting pressure.
Pressure (atm) Volume (mL) 1/Volume pressure x volume
































Attach Graph: Graph 1 = pressure vs. volume
Graph 2 = pressure vs. 1/volume
One of the graphs will plot a curve, the other will plot a straight line.
Using the straight line graph and the slope intercept from (Y = mX + b), derive an equation relating pressure and volume. This equation is Boyles Law. (Help)
Boyle’s Law Equation:
Slope of Graph Line (m)
The slope of straight graph line is a ______________________________
How does the slope of your graph compare to the values of Pressure x Volume determined from your data? (Help)
Describe the proportional relationship between pressure and volume.
