Introduction

The purpose of this investigation is to conduct a series of experiments, each of which illustrates a different gas law. You will be given a list of equipment and materials and some general guidelines to help you get started with each experiment. Four properties of gases will be investigated: pressure, volume, temperature, and number of molecules. By assembling the equipment, conducting the appropriate tests, and analyzing your data and observations, you will be able to describe the gas laws, both qualitatively and mathematically.

Objectives

In this experiment, you will

  • Conduct a set of experiments, each of which illustrates a gas law.
  • Gather data to identify the gas law described by each activity.
  • Complete the calculations necessary to evaluate the gas law in each activity.
  • From your results, derive a single mathematical relationship that relates pressure, volume, temperature, and number of molecules.
