Pressure and Volume with a Syringe and Flask

Submitted by PocketLab on Fri, 06/02/2017 - 16:44

Exploration

Explore air pressure, temperature, and volume and how they work together. In a syringe sealed to an Erlenmeyer flask , when the syringe’s plunger moves back and forth, the volume of air in the syringe and f ask changes. Will the pressure also change if the temperature of the air sealed in the syringe and f ask changes? A PocketLab can be placed inside the Erlenmeyer f ask to measure the change in pressure as the the volume and temperature change. 

Objective

In this experiment, students will:
1. Develop a model that describes the relationship between air pressure, volume, and temperature.
2. Describe what is happening to the air particles when there is a greater or less air pressure.
3. Describe what is happening to the air particles when there are changes in temperature and how that relates to the measurement of temperature itself.
