Unit 4, Lab 2: Boyle’s Law
Name: Date:
Experiment 1: Determine the Relationship Between the Volume and Pressure of Propane gas
Lab Results
1. Record the pairs of data for pressure and propane volume in the table below.
Volume of Gas (mL)
Pressure (atm)
Data Analysis
2. Create and save a graph of pressure in atm (y-axis) versus the 1/volume of propane in 1/mL (x-axis).
3. What pressure would the propane gas sample have at 80mL?
Experiment 2: Determine the Relationship Between the Volume and Pressure of Butane gas
Lab Results
1. Record the pairs of data for pressure and butane volume in the table below.
Volume of Gas (mL)
Pressure (atm)
Data Analysis
2. Create and save a graph of pressure in atm (y-axis) versus the 1/volume of butane in 1/mL (x-axis).
3. What pressure would the butane gas sample have at 140 mL?
4. What volume would the butane gas sample occupy at a pressure of 2.05 atm?
Conclusions
1. How did the data from the two experiments differ?
2. How would you expect a sample of pentane to behave under similar experimental conditions?
3. The bubble wrap shown in the figure below is often used to protect fragile objects during shipping. Bubble wrap tends to pop when stepped onto or squeezed. How can you explain this using Boyle’s Law? http://static.latenitelabs.com/production/assignment_media/800px-puchipuchi.jpg
