The Physics Philes, lesson 126: Kinetic-Molecular Model of Ideal Gases, Part 1

As promised, this week we’ll start a discussion on the kinetic-molecular model of ideal gases. Be warned: we’ll have to take this in chunks. Now that that’s out of the way…what is the kinetic-molecular model of idea gases? Basically, it’s a way to understand the properties of a bunch of …
