We have learned over the past few weeks that gases have real-life constraints on how they move here in the non-ideal world. As with most things in chemistry (and also in life), how a gas moves is more complex than it seems at first. In this episode, Hank describes what it means when we talk about the velocity of a gas - to understand gas velocity, we have to know what factors affect it, and how. Hank also teaches you about effusion, diffusion, and concentration gradients, before showing off a cool experiment that physically demonstrates the things you have just learned. Sound exciting enough for you? Let's get started. *Special Thanks to Matt Young at the University of Montana (Geosciences Department, Environmental Biogeochemistry Lab) who helped with the chemical demonstrations.* Pssst... we made flashcards to help you review the content in this episode!
