Gas laws and kinetic molecular theory

If you need to know about gases, you’ve come to the right place with these tutorials! (Updated 6-7-22)

  • Kinetic molecular theory:  To understand the properties of gases, we need to understand how they behave on an atomic level.  Don’t worry:  You won’t have to count all of the atoms.
  • Kinetic Molecular Theory PowerPoint:  The above, but in PowerPoint form.
  • Basic gas laws:  Boyle, Charles, and Gay-Lussac all came up with laws to describe gases. That Avogadro guy did, too.  But if you really want to save time, learn about the combined gas law.
  • The ideal gas law:  This really gets to the heart of how gases behave.  Though the derivation involves statistical mechanics, we won’t deal with that here (you’ll hear about it enough in grad school – trust me).
  • Gas Laws PowerPoint:  A whirlwind tour though the world of Boyle, Gay-Lussac, Charles, combined, and ideal gas laws.
  • Gas stoichiometry:  What do you do when liters and grams are put into the same problem?  Why, you read this tutorial, of course.
  • Let loose the gases!  This tutorial covers the main gas laws and gas stoichiometry – also from my unpublished textbook.
  • States of matter and phase changes:  In addition to the topics named here, it also discusses the kinetic molecular theory of gases, Graham’s law, and RMS velocity. I’m putting it here, for these reasons, and because I want to.

Supplemental videos:  These videos are all over at the amazing Crash Course YouTube channel.  I didn’t make these, though I wish I did.
