Features 23 core lab activities that cover the fundamental concepts of Force & Motion, Energy Transfer, Electricity & Circuits, Fluids and more.
Use an absolute pressure sensor to investigate the effect of changes in the volume of a confined gas on pressure at constant temperature.
Students investigate the effect of changes in the volume of a confined gas on pressure at constant temperature. Using the pressure sensor, students observe simple tables or graphs and compare the change of pressure with varying volume.
Students measure the change in pressure by varying the volume of trapped air in a syringe while:
- Understanding that substances have characteristic properties, such as density, a boiling point, and solubility, all of which are independent of the amount of the sample
- Realizing that energy is a property of many gases and is associated with heat and mechanical motion
- Observing the relationship between volume of a gas and the resulting pressure in a container
- Gaining skills and confidence in using a scientific measurement tool, the pressure sensor, as well as the spreadsheet and graphing capacity of a computer to represent and analyze data
Students gain experience conducting the following procedures:
- Setting up the equipment and work area to measure the change in pressure in a syringe as the volume is changed
- Measure the pressure in a syringe while decreasing and then increasing the volume in 2-mL increments
- Using math skills to obtain a linear relationship between pressure and volume by computing the inverse of pressure and plotting the resulting values versus volume
