What is Boyle's Law?
Objectives, Materials, and Procedures
1. Use gas pressure sensor and gas syringe to measure the pressure of air at different volumes.
2. Use the date to be able to determine the relationship between pressure and gas.
3. Describe the relationship between volume and pressure using the mathematical formula.
4. Use the results here to be able to predict the pressure at other volumes.
2. Gas syringe (20 mL)
3. gas sensor and computer interface
4. Logger Pro software
1. Prepare the Gas Pressure Sensor and an air sample for data collection. do this by connecting the sensor to your computer and connecting the syringe to the sensor with the syringe being at the 10 mL mark.
2. now click collect, make sure you watch the syringe make sure you are getting the best data possible.
3.now collect the date for pressure VS volume. it is best if one person deals with the syringe while another deals with the computer.
4. do this tell your reading is stable then click keep, remember you are adding .8 to the volume for the total number
5. you will repeat steps 1 - 4 for 7.0 mL, 9.0 mL, 11.0 mL, 13.0 mL, 15.0 mL, and 17.0 mL remembering to add .8 to each one. once this is done hit stop.
6. In your data table record the pressure and volume pairs you see on the graph
7.study the date of pressure and volume and decide how you think these to respond to each other.
8. Once this is done add a line of best fit, by using the "best fit" button in the corner.
9.Once you have the graph is an inverse or direct relationship you can print it and go on to answering the questions.
