Ch 7: Gases

These video lessons on gases will teach you about kinetic molecular theory, Dalton's law, Avogadro's law, the ideal gas law and more. Each lesson is accompanied by a short multiple-choice quiz you can use to check your understanding of these topics.

Gases - Chapter Summary and Learning Objectives

Learn about gases with our bite-sized videos. We'll use the kinetic molecular theory to explain the movement of gas particles and examine how the effects of random particle collisions at different velocities leads to an orderly picture of the overall properties of gases.

The video lessons in this chapter simplify the scientific laws and concepts involving gas pressure, temperature and volume. If you need some extra assistance before taking the self-assessment lesson quizzes, you can submit questions to our instructors. As you make your way through the videos, you will:

• Study the properties of real gases and examine their behaviors
• Learn about effusion, diffusion and how to calculate the relative velocities of gases
• Examine the relationships between the volume, temperature and pressure of a gas
• Learn about the standard units of pressure and temperature
• Master the numerous laws and theories that govern our understanding of gases
