Learning Activities 5.1 – 5.3: Equilibrium Vapor Pressure of Water
![](local/data/caches/images/scaled/img_00034508_300x300.png)
This 7-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. The activity has students measure the equilibrium vapor pressure of different temperatures of water by boiling water in the chamber of a Rough Vacuum Equipment Trainer (RVET).
A summary of learning activities, learning objectives, a suggested pre-lab assignment, theoretical background, the activity procedure, and more are included. Student learning outcomes include:
- Collect data to qualitatively assess water’s changing equilibrium vapor pressure changes in the temperature of the liquid water.
- Recognize that once the pressure at which the boiling point of water occurs, achieving lower pressures in the vacuum system corresponds to the decreasing temperature state of the water
- Report calculated values with appropriate significant figures.
The E-book, laboratory manuals, other learning activities, and related videos are available to view separately.
