The Ideal Gas Law: Crash Course Chemistry #12

Gases are everywhere, and this is good news and bad news for chemists. The good news: when they are behaving themselves, it's extremely easy to describe their behavior theoretically, experimentally, and mathematically. The bad news is they almost never behave themselves.
In this episode of Crash Course Chemistry, Hank tells how the work of some amazing thinkers combined to produce the Ideal Gas Law, how none of those people were Robert Boyle, and how the ideal gas equation allows you to find out pressure, volume, temperature, or number of moles. You'll also get a quick introduction to a few jargon-y phrases to help you sound like you know what you're talking about.

At 5:37 - decreasing the number of miles decreases the volume, but in the case of a balloon the pressure actually goes up because pressure is related to curvature (this is why it's hardest to blow up a balloon when you're starting it and then it gets easier).

A chemist froze himself at-273C. Everyone said he was crazy. But he was 0K

We were watching this in class and the teacher pause it right after the "They almost never behave themselves, " and she just looks at us and goes, "Can't imagine what that's like."

The fact that this video is 5 years old and that im going to university now and still use these as an aid in studying physics goes a long way to show how well made and timeless these videos are, cheers for that

If I had a dollar for every time I had a test tomorrow and Crash Course saved my butt ...

PV=nRT, or as I remember it, "PerVneRT".

Anyone else struggling in Chem rn lmao

0:25 not me actually waving my hands around to see if i could feel it 😭

On Henry Power's wiki page, it says:
"Written by Hank Green, saviour of impoverished high school children."




Well played, Hank.

Hank: DO YOU FEEL IT? ARE YOU DOING THIS?!
Me: I'M DOING IT! :D

In eight years of chemistry I have never seen the can experiment, and that made me really happy to see something so simple but so new to me

I did shake my hands around. And I did feel it

[nataliecampos]

I like that you broke down each portion of the ideal gas law equation. Keep up the good work :)

[sweetlolitaChii]

Did anyone else wave their hands around when Hank did? XD

[AllKindzzzz]

This is an excellent episode of CC. Great job Hank and all of the CC team. Took me months to get my head round this at degree level. Wishing I'd seen this sooner.

Exams got me watching 46 crash course chemistry vids after finishing all of world history and economics.

2:58 thank you, you have probably helped thousands of students from that, and thank you for your videos which help millions.
