Virtual Lab – Exploring the Relationship Between P, V and T for Ideal Gases
In this lab, you will explore the relationship between Pressure, Volume, and Temperature of an Ideal Gas. Fully answer the questions below and submit them to your instructor.
Use the PhET simulation ( https://phet.colorado.edu/sims/html/gas-properties/latest/gas-properties_en.html ) to answer these questions. Click the “Ideal” icon at the link.
a. Add gas to the chamber, by moving the pump lever up and down.
b. Hold the temperature constant and decrease the volume. What happens to the pressure? Explain why the pressure changed based on the number of collisions between particles and between particles and the wall of the chamber.
c. Hold the volume constant and increase the temperature. What happens to the pressure? Explain why the pressure changed in terms of particle collisions.
d. Hold the volume constant and increase the number of particles. What happens to the pressure? Explain why in terms of particle collisions.
e. Hold the pressure constant, while allowing the volume to change, and increase the number of particles. What happens to the volume? Explain why in terms of particle collisions. How does this compare to what happens when you blow up a balloon?
