Real Gases: Crash Course Chemistry #14

Hank bursts our ideal gas law bubble, er, balloon, and brings us back to reality, explaining how the constants in the gas law aren't all that constant; how the ideal gas law we've spent the past two weeks with has to be corrected for volume because atoms and molecules take up space and for pressure because they're attracted to each other; that Einstein was behind a lot more of what we know today than most people realize; and how a Dutch scientist named Johannes van der Waals figured out those correction factors in the late 19th century and earned a Nobel Prize for his efforts.

I love how crash course throws in all the history behind the names of laws and units that Ive been hearing since hight school. I dint know why, but learning about the story behind the equations makes it more exciting, and thus easier for me to understand. Thanks CC!

it's 4:33 am what started out as review for a biology test has turned into a science binge. science is awesome

the awesome hank green - teaching life advice to teenagers through gas laws.

[BrainBuzzer]

Don't know why, but I am starting to love chemistry. :) Thanks Hank.

[muisho]

oh my god this man is a Living Saint. He explains thats so that I can understand them so much better. Hes actually better than the Chemistry teacher that I had in High School. I can honestly say that my interest in Chemistry is solely from him.

Becoming the director of a school = suddenly realizing that you are Dumbledore. Sweet.

Hank, I want to thank you for this series of videos (which I have been bingeing for the last 2 hours). I've been a professional brewer for a number of years, and recently I decided to enroll at my local college to study biochemistry in order to further my career. I start Chemistry lab work next week. Your sign-off message of never giving up on one's dreams because of the potential that they offer, even for a 30-year old working-class scientist, is just what I needed to hear right now. The cost of tuition is a dear price to a person who works full time, and I hesitated to pay it willingly. But now I find myself resonating strongly with the story of Van Der Waals, old as it is. I have followed SciShow since the early days purely for entertainment, but now you have given me something more than either entertainment or academic knowledge, you have offered me encouragement. Thank you.

(P.S. Can you recommend any high-quality Periodic Tables for home use and display? I can see you are a fan!)

That awesome guy in the Video !
Keep it up ! Man !

This video was sponsored by CGP Grey. :P

CGP Grey's shirt? That man is as informative as you! And you should continue to become a teacher of any sort!

I watched CC Physics, and then CC Chemistry again, and then wished Hank would host CC Physics.

what a motivational tale...I'm in tears 👏

12 200 kPa - 11 800 kPa =/= 3 000 kPa, but 400 kPa.
Unless I missed something or didn't understand the units, there, I think you got this wrong.
I'm pretty sure I'm not the first to point this out, though, but I didn't go through the 530+ other comments.
Also, I still really love your show, and I'm _so_ excited to vicariously aid in the YouTube education of other viewers by subscribing to you on Subbable (seriously, you're awesome)! :D

Man you do not know the struggle of high school until you do the IB diploma. That shit is cray cray. Speaking of which, these crash courses are fabulous!! Good work!

[shaboatrad]

I know it's a stupid comment in the middle of chem, but Hank Green Your smile is pretty nice
almost everytime he smiles I smile too!
Good job guys
the writer has done an amazing job to make it fascinating!
Thank you Crashcorse I've learned a lot! !!
and good news I am accepted in the Biology Olympiad by Watching crashcorse and finishing all my text books!
Tnx A LOT!!

[TheGmoney]

Would love a FULL episode of Hank, John, & CPG! That would be awsome!

[sjwimmel]

I like the way you related chemistry to real life. It was actually kind of inspirational, teachers should do that more often.
