Chemistry through Inquiry Teacher Guide

(PS-2871C)

Features over 25 inquiry based labs covering the fundamental concepts of lab skills, structure & properties of matter, chemical reactions and more.

Boyle's Law

Lab Summary

Use an absolute pressure sensor to determine the effect of volume on the
pressure of a closed system containing a fixed amount of molecules at a
constant temperature.

Theory

Determine the effect of volume on the pressure of a closed system containing a fixed amount of molecules at a constant temperature. Through this investigation, students:

  • Show that an inversely proportional relationship exists between pressure and volume for a gas at a constant temperature.
  • Apply Boyle’s law PV = k and P1V1 = P2V2
  • Differentiate between real and ideal gases

 

Method

Students conduct the following procedures:

  • Use an absolute pressure sensor to determine the pressure of a fixed sample of air molecules at various volumes.
  • Collect data in replicate and calculate averages.
  • Graph volume versus pressure of a fixed amount of gas molecules at a constant temperature.

Sensors / Equipment Used:

PASPORT Chemistry Sensor
