Interactive Self-Study Module: Ideal Gas Law
Department of Chemical and Biological Engineering, University of Colorado Boulder 

This module uses screencasts and interactive simulations to explain the relation between temperature, pressure, and volume for ideal gases, including mixtures. It then provides example problems and ConcepTests to allow the user to test themselves. We suggest using the learning resources in the following order:

  1. Attempt to answer the multiple-choice ConcepTests before watching the screencasts or working with the simulations.
  2. Watch the screencasts that describe ideal gas properties and provide an overview of standard temperature and pressure and answer the questions within the first screencast.
  3. Try to solve the two example problems before watching the solutions in the screencasts.
  4. Answer the ConcepTests.

Ideal gases are good first approximations for real gases.

This module is intended for a materials and energy balance course.

Before studying this module, you should:

  • Be familiar with general chemistry

After studying this module, you should be able to:
  1. Solve problems using the ideal gas law.
  2. Know when a gas can be assumed to be ideal.
