Passing Gases: Effusion, Diffusion, and the Velocity of a Gas - Crash Course Chemistry #16

Rating: 4.0; Vote: 1
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 at first appears. 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 effect 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! Find them on the free Crash Course App!

Do you have any crash courses in mathematics?
I used to love math. until junior high. when I had a math teacher that acted alot like Snape, a science teacher obsessed with mushrooms, and that's not even going into the english teacher who knoew less english than me, and the other teacher who thought telling a bunch of teenager to do whatever they wanted as long as they didn't disturb those who wanted to learn. >>
So, yeah. I really could use a good basic course in math covering junior high and high school math, and I bet alot of other people had much the same problem. (Tho maybe for different reasons) And finding a free GOOD math course online seems nearly impossible. >>
Plus, I love the chemistry teacher here, despite his speed-spech, and the way to make everything come to live in CrashCourse, so.

- Doesn't attend a single Chem lecture - - Gets 28 lecture behind - - Exam in 2 days - - Watches Crash Course on 1. 5x speed - GETS A 68 and a CREDIT! THANKYOU.

These videos are literally the only reason I passed the AP chem test four years ago, and they're also the reason why I'm at the top of my class in college Chemistry.
