Kinetic Molecular Theory and its Postulates
We learned about ideal gases and the ideal gas laws, and we briefly touched on kinetic molecular theory, which puts these laws in context. But let's now go through this theory more rigorously, analyzing each postulate one at a time.

Kinetic Molecular Theory and the Ideal Gas Laws
I bet many of you think that the ideal gas law must prohibit passing gas on the elevator. That's a very good guideline, but there are other important laws we must know! Let Professor Dave run you through the details.

Non-Ideal Gases and the Van der Waals Equation
We learned about ideal gases, as well as kinetic molecular theory, which explains the laws that govern ideal gases. But some of the postulates of this theory won't always hold true. When a gas is highly pressurized and/or very cold, it...
