Learning Activities 4.3: Gas Pressure and Boyle’s Gas Law

This 6-page learning activity is from the Introduction to Vacuum Technology Student and Instructor Laboratory Manuals that accompany the Introduction to Vacuum Technology E-Book published by Erie Community College. This activity has students "measur[e] the volume of two sample materials, shaving cream and marshmallows, at atmospheric pressure and a vacuum pressure level." Students also use pressure and volume data to verify Boyles' law.

The activity includes a summary, learning objectives, a pre-lab assignment, theoretical background, a list of equipment and materials needed, and the activity procedure. Student learning objectives include:

1. Perform the pump-down sequence for the RVET system.
2. Collect pressure data points from the RVET system pressure gauges and volume data points for the sample materials.
3. Use scientific notation to represent numbers.
4. Apply rules of significant figures (digits) through unit conversion practice.
5. Calculate the percent difference between the initial and final PV products.
6. Verify Boyle's law.

The E-book, laboratory manuals, other learning activities, and related videos are available to view separately.
