Gas Laws

Lab Summary

Use an absolute pressure sensor to observe changes in pressures and volumes of gases as they apply to Boyle’s law.

Theory

Conduct an experiment to observe changes in pressures and volumes of gases as they apply to Boyle’s law. Students explore the concept of Boyle's law by:

  • Studying the relationship between the volume and pressure of an enclosed gas.
  • Graphing this relationship and deriving an equation relating the pressure to the volume of an enclosed gas.
  • Accurately predicting the behavior of a gas using Boyle's law.

Method

Students gain experience conducting the following procedures:

  • Manually gathering data for pressure and volume for a compressed gas.
  • Constructing a graph of pressure versus volume and manipulating the data to derive a linear relationship between pressure and volume.
  • Understanding the work done on a gas and the work done by a gas as they relate to the graph of pressure versus volume.
