Boyle's Law

Lab Summary

Use an absolute pressure sensor to observe the relationship between volume and pressure of an enclosed gas at constant temperature.

Theory

Students observe changes in pressures and volumes of gases as they apply to Boyle’s Law. At the end of this lab, students:

  • Understand the relationship between volume and pressure of an enclosed gas at constant temperature.
  • Are able to graph this relationship and derive an equation relating pressure and volume of an enclosed gas.
  • Apply the equation to predict gas behavior using Boyle's Law.

Method

Students will gain experience conducting the following procedures:

  • Decrease the volume of the gas in a closed system causing pressure to increase.
  • Enclose gas with a 20ml syringe and pressure sensor and decrease the volume increasing pressure.
  • Linearization of data to determine the nature of a relationship between to variables.
