Activity 2
Boyle’s Law
Objective:
•
Investigate the relationship between volume and pressure of gases at constant temperature.
Materials:
Computer
Procedure:
1. Open the site
http://group.chem.iastate.edu/Greenbowe/sections/projectfolder/flashfiles/gaslaw/boyles_law
_graph.html to get started with the activity.
2. As the site is opened, drag the plunger to your desired volume and observe what happens to the
pressure reading.
3. Record the pressure and volume reading using Table 5.

Q2. What happens to the pressure when the amount of volume is changed?
Q3. As you continue decreasing the amount of volume, what happens to the pressure?
4. Plot a graph with the pressure at the y axis and volume at the x axis using Microsoft excel.
Q3. Describe the graph.
Q4. What is the relationship between volume and pressure of gases at constant temperature?
