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!
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.
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!)
9:54 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 TH-cam education of other viewers by subscribing to you on Subbable (seriously, you're awesome)! :D
Back in what day? There are many ways of receiving education without a formal institution, this youtube channel is one of them. It is never bad to educate yourself without reaching for a degree. Gaining general knowledge is always good.
02-20-24 Still great after ten years! I dropped out of High School before taking chemistry.I am 74 and new to learning about chemistry. Hypothetical Ideal Circumstances and Real life. New Tricks.Van Der Walls Equation. How to calculate under circumstances that are not "ideal". Can't get Nobel Prize after you die! 7:05 Correct Equation. 10:38 Summary.
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!
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!!
Hey John and everyone else. John, you said "You should never give up just because things are hard or people think that your ides are crazy". Here is an idea that I have been playing with for awhile but don't know that it can be done.--- EPIM [Extreme Pressure Ice Molding] - The idea is to compress prepared and mixed elements in molds made of ice at very low temperatures [-200 degrees and lower] - introduce an increase in temperature to the compressed elements and cause them to form products. ---- Example; Suppose I wanted to make a Hammer head from Iron with .5% Sulfur and .2% Chlorine. ----- 1st I would carve in a block of ice the shape of a Hammer head. - 2nd I would prepare the elements [separate into very small components at very low temperatures -200 degrees and lower] and ionize them if necessary. 3rd I would mix the elements and place into the mold. 4th I would compress the elements and lock the mold. 5th I would cause an increase in the temperature of the prepared elements of the mold causing them to bond. Afterword’s I would bring the mold up to room temperature - the ice would melt and I would have a hammer head. Can this idea be made to work
+Nihar Baijal Tried, I can't get a simple answer to a single question; A single atom of carbon at room temperature has a volume. The question is this; What is the volume of that atom at the temperature of liquid Hydrogen?
+Nihar Baijal Boy, that really challenges my understanding. We used to install bearings in undersized holes with liquid nitrogen - The holes got larger {contracted} and the bearing got smaller {contracted}. When the came back to room temperature they made a perfect bond. I guess this only applies to bearings.
So I seriously love this series and chemistry and it's pushing me towards a chemistry major for my sophomore year of undergrad :) Thanks Hank and the rest of the creators
I learned about what conditions the ideal gas law falters in during high school, but the class didn't study this more realistic form of the law in detail, so thanks for covering it! Also, I'm with everyone who says that after you've finished chemistry, a crash course on physics or astrophysics or something of the sort would be awesome.
I didn't know that studying for my chem test would bring a life lesson and motivation talk with it but u know what I'm not mad and of course Hank is the one to do it
I think you should do Crash Course Calculus. I'm really wanting to learn it because it interests me and I haven't gotten to an official calculus class yet. Crash Course is really good at making the hard parts of subjects easier to learn. When I do get to calculus in regular lessons, I want to be sure that I'm learning it.
Hank's kid is going to be so lucky. That beginning speech sums up every teenage vs adult problem ever--yes, adult world is tough, but do not belittle our lives, our efforts
Correct. However in practice with elements lighter than iron fusion occurs before this point and the process becomes harder and harder now because the pressure decreases of the system naturally decreases as the rate of fusion increases. That is until you reach a point where such interactions are impossible.
I thought kryptonite was a piece of Krypton? That was what I was thinking of, a solid piece of Krypton. However, since you mention the crystallization idea, I now have two ways of getting myself to the point where I can justify making the shirt. Awesome! The TH-cam community: Teaching the masses, so long as you watch videos like these.
In my opinion, it's a good kind of advertising. CGPgrey, Hank Green and all other youtubers give us all this knowledge and interesting facts for basically nothing except for few ads now and then. I strongly support supporting (hehe, weird choice of words) our favourite youtubers by buying the gear they created for us! It's a nice cycle. We like their videos, buy their stuff and in return they have the means to make more videos for us. :)
Now I'm wondering where we even got the values for a and b for each gas. My head currently hurts from binge watching crash courses and the only thing I'd been able to find so far is a chart of the a and b values for various gases, but I was hoping someone could explain HOW we found those values in the first place or at all.
I think there is more in the Van der Waals equation than experimental factors. Although it required Physics that accepted molecules, the experimental factors are related to dipole moments of molecules, which can be theoretically calculated.
In addition to just clicking the up thumb to negate your down thumb, you can also re-click a rating to remove it completely and return to a neutral rating state.
I agree. As I stated in my other comment, the schwarzchild radius of all of the gas in the given space is the theoretical limit, even if you could keep the temperature the same. However, it is usually so small for our purposes that it does not make much of a difference. I apologize for jumping in the middle of the conversation- I did not see that this already was part of one.
It is a introduction video to " real gases". In fact only few of them are really described by this equation. Other equations offer better approximations to real gases ( Redlich-kwong-soave, Peng-robinson, Viral...)
Argh - graph without axes labels at 4:20. Vertical axis implied strongly from context as PV/nRT (often expressed as the compressibility factor Z), horizontal axis only briefly touched on as pressure after the graphic has gone.
Because it is much easier to use, since you would need to learn every correction factors for every gas to calculate correctly. Although it might be no problem for computers, it is good for the students who are learning it.
Actually I believe there is a limit to how much you can compress a substance. This is called the schwarzschild radius, when an object is condensed so much that its escape velocity exceeds the speed of light and a black hole is formed.
It might be that I'm from the northern part of the Netherlands where things are pronounced 'harder' but van der Waals has a very clear W in it when pronounced over here. And because of the van der Waals forces it is actually something I have heard pronounced quite a few times.
Not much of an advertisement if the only ones who recognize the image are those who already watch CGPGrey's videos. It's more like a sign of respect, a tribute.
I find it interesting you have been able to go through all of this, and wonder how long it will last, without using the D word. yes, differential equations.
6:18. Actually, the net forces between molecules in a gas are repulsive, not attractive. That's why there is a plus sign for the correction factor to pressure: repulsion increases pressure. If the forces were attractive, pressure would decrease (the pressure correction factor would have a minus sign like the volume correction factor).
The forces are attractive. The P used in the van der Waals equation is the observed pressure, which is the pressure (calculated using the volume correction) minus a correction factor. If you do some substitution, you find that P(observed)=P - correction P(observed)= [nRT]/[V-nb]-correction factor P(observed) + correction factor= [nRT]/[V-nb] While the correction factor is added to P in the adjusted equation, this doesn't mean that the real pressure is higher than the ideal pressure.
Ok, I see were I was confused. I was thinking of the (P-correction) as the observed pressure. I was thinking that because, for the volume, hank said "the particles take up space, decreasing available volume", and then "inter-molecular attractions decrease pressure" (both said decreasing), but only one had a minus sign. I realize now that's because (V-correction) is effective volume for the molecules and (P+correction) is what the pressure would have been with a volume of (V-correction). What I still don't get is why the force is attractive. I know there is the attractive van der waals force, but that is rather weak, and there is also strong repulsion from Pauli repulsion. Just looking at a graph (en.wikipedia.org/wiki/Lennard-Jones_potential) It looks like the repulsion would dominate on the average.
after thinking about it some more, I think what I was calling the repulsion was taken into account in the VOLUME correction term. 'correcting the volume' is due to the REPULSION not 'letting other particles near it'. so, if V is the volume of the container and P the observed pressure, re-arranging as you did, you get P(observed)= [nRT]/[V-nb]-correction factor but, the -nb in the denominator decreases the denominator (from that of the ideal gas), which increases the first and positive term for P(observed) while the - (pressure) correction factor decreases it.
I could, ironically, turn that question back to you. Hank's comment was part of a humorous analogy between the idealized circumstances adults foist on kids relation to the realities of adult life vs the ideal gas law and the more complex realities. I in turn made an, admittedly barbed, humorous response based on the fact that most adults don't really have any more money than a kids allowance after paying to sustain their life, with a statement on the value of that idealized arrangement.
indeed, internet based learning channels are desperately needed in a world suffering from The History Channel Effect. CGPgrey, Crash Course and others are excellent channels.
Well that's the point. He/she asked if you could convert a gas into a liquid by raising the pressure (as opposed to lowering the temperature) and you can because pressure and temperature are proportional in most cases. However in a hypothetical scenario where one might increase the pressure without increasing the temperature there is almost no limit to the amount one could compress something even if it's a gas at room temperature.

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!
izuka kind of understandable considering how our brain works. Association, association association
izuka high*, didn’t*
me to
it's 4:33 am what started out as review for a biology test has turned into a science binge. science is awesome
True
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.
the awesome hank green - teaching life advice to teenagers through gas laws.
eheheeh
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.

Thank you.
(P.S. Can you recommend any high-quality Periodic Tables for home use and display? I can see you are a fan!)
Don't know why, but I am starting to love chemistry. :) Thanks Hank.
then you finally know that you are starting to succeed at life:)
That was temporary. When mybteacher started teaching those new things which are not covered, my life sucks.
look through scishow, I haven't watched their videos much, but it's Hank there too, so it might be helpful
Annnnd The Nobel Price for explaining science goes to ...
That awesome guy in the Video !
Keep it up ! Man !
Becoming the director of a school = suddenly realizing that you are Dumbledore. Sweet.
i was gonna say that! but you were three years early lol

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.

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!
I like the way you related chemistry to real life. It was actually kind of inspirational, teachers should do that more often.
CGP Grey's shirt? That man is as informative as you! And you should continue to become a teacher of any sort!
Would love a FULL episode of Hank,John, & CPG! That would be awsome!
* decides to fall asleep listening to the CC Chem playlist to study for AP Chem finals *
* somebody help my soul *
I do it all the time'
what a motivational tale...I'm in tears 👏
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!!
If you want to watch him smile more, then watch vlogbrothers, and pretty much all you will see will be Hank smiling
02:36 oh my gosh it's Dumbledore! I love Dumbledore!

You just helped me soon much for my AP chem test. Thank you!
Thanx for that mini-speech at the end, extremely relevant I would say :).
Thank you Hank for the intro talk, really makes me feel beter.
I watched CC Physics, and then CC Chemistry again, and then wished Hank would host CC Physics.
SAMEEE
Correct
Same
Shini Somara is a great host too :/
Wow!...this was like one of best episodes of crash course....really enjoyed it!
I love how hank is wearing a cgp grey t shirt, because cgp grey also talks about the school thing in hello Internet :0
THat was the longest analogy ever.
I was JUST ABOUT TO comment the same thing. :(FFFFffffffffffffffffffffffffffffffffffffffffffffffffffffffuk
indeed looongg
facts
And the same goes for gases. 🙂 OF COURSE
That caught me off guard
So I seriously love this series and chemistry and it's pushing me towards a chemistry major for my sophomore year of undergrad :) Thanks Hank and the rest of the creators
The way he talked at 8:20 made me laugh so hard.
Now, people are staring at me.
the next time I can't fall asleep, definitely gonna watch this video😁
(love you - crash course guy, it's just that this video is strangely relaxing)
I love how your intros are all about life or waking up in belgium by chance one morning and yet you manage to relate them to chemistry!
You're videos have helped me pass chemistry this year!! Can you make a physics crashcourse next year?
I learned about what conditions the ideal gas law falters in during high school, but the class didn't study this more realistic form of the law in detail, so thanks for covering it!

Normally it's hard for me to understand things like this, but you explained it really well and I get it (nearly) completely! Thanks!
I watched this while wearing the same CGPGrey T-Shirt.
I FEEL SO VALIDATED
My lecturer at uiversity uses a lot of your videos to help teach the basics, its good stuff and it helps a lot!!
This video was sponsored by CGP Grey. :P
Hank and I are wearing the same shirt!
GGP grey + Hank Green + Crash course + Me ---> a very wonderful chemical equation.
You were definitely taught this in AP, i just took AP chem this year and this equation is still fresh in my mind
good vid, man =]
this is the first chem concept from this course that I never learned in any of my schooling, Looking forward to more!
I think you should do Crash Course Calculus. I'm really wanting to learn it because it interests me and I haven't gotten to an official calculus class yet. Crash Course is really good at making the hard parts of subjects easier to learn. When I do get to calculus in regular lessons, I want to be sure that I'm learning it.
CGP Grey T-shirt!
If I ever met John or Hank in real life, I would cry. I would cry my tear ducts dry. I love them for what they do.
When i get to college i am taking every class in science.
hope you don't live in the US
Hank's kid is going to be so lucky. That beginning speech sums up every teenage vs adult problem ever--yes, adult world is tough, but do not belittle our lives, our efforts
wow...now I have huge respect for van der Waal
Graphics as usual, are spot on.
I appreciate the GCP Gray T shirt in this video :)
GCP Gray? Or CGP Grey?
Marie Bondy You're hot.
How did Van der Waals manage to turn into Dumbledore?
He ate his vegetables and worked hard.
chibidrin According to Spiderman, if you eat your green vegetables, you can be like him, too.
thats cause he is owned by dishy
Magic... O3O
Yes
Correct. However in practice with elements lighter than iron fusion occurs before this point and the process becomes harder and harder now because the pressure decreases of the system naturally decreases as the rate of fusion increases.

Is it bad that this stuff goes over my head, but I still like watching?
nice analogy and clarify more things in details
I think there is more in the Van der Waals equation than experimental factors. Although it required Physics that accepted molecules, the experimental factors are related to dipole moments of molecules, which can be theoretically calculated.
Thank you much for these series btw!! used them in bio last year and using now in chem. Love how its explained, u guys are awesome!
In addition to just clicking the up thumb to negate your down thumb, you can also re-click a rating to remove it completely and return to a neutral rating state.
I agree. As I stated in my other comment, the schwarzchild radius of all of the gas in the given space is the theoretical limit, even if you could keep the temperature the same. However, it is usually so small for our purposes that it does not make much of a difference. I apologize for jumping in the middle of the conversation- I did not see that this already was part of one.
Finally, a chemistry crash course where I could follow the logic and math from start to finish
It is a introduction video to " real gases". In fact only few of them are really described by this equation. Other equations offer better approximations to real gases ( Redlich-kwong-soave, Peng-robinson, Viral...)
Chemistry is awesome!
I adore your videos. Even though I am not taking chemistry, you make it interesting for me. Thanks and DFTBA.
Argh - graph without axes labels at 4:20. Vertical axis implied strongly from context as PV/nRT (often expressed as the compressibility factor Z), horizontal axis only briefly touched on as pressure after the graphic has gone.
united by learning and teaching, pass it on.
I just got back from my last ever day of highschool and am studying for finals and hank goes and says that, wow
Because it is much easier to use, since you would need to learn every correction factors for every gas to calculate correctly. Although it might be no problem for computers, it is good for the students who are learning it.
I love the transition at the beginning!
Actually I believe there is a limit to how much you can compress a substance. This is called the schwarzschild radius, when an object is condensed so much that its escape velocity exceeds the speed of light and a black hole is formed.
It might be that I'm from the northern part of the Netherlands where things are pronounced 'harder' but van der Waals has a very clear W in it when pronounced over here. And because of the van der Waals forces it is actually something I have heard pronounced quite a few times.
the story is inspiring thanks for including the history...probably the only kind of history im interested in...
Hank....I learned more about the Van der Walls equation in this video than when my Thermodynamics professor taught it. Thank you.
PV=nRT is correct since V-nb=V since nb is nobody.
The segue in the beginning was absolutely pro

Despite all this, CGPgrey deserves this. He is awesome :D
i have a quiz on this tomorrow so thanks for this!
Life lesson on growing up with a side of scientific information on real gases
indeed, internet based learning channels are desperately needed in a world suffering from The History Channel Effect. CGPgrey, Crash Course and others are excellent channels.
Love CPG grey!!!!!!!!!!!!!!!! nd the shirt, Hank!!!
I have my Chemistry final tomorrow. Thanks for helping me understand stuff!
Well that's the point.
He/she asked if you could convert a gas into a liquid by raising the pressure (as opposed to lowering the temperature) and you can because pressure and temperature are proportional in most cases.
However in a hypothetical scenario where one might increase the pressure without increasing the temperature there is almost no limit to the amount one could compress something even if it's a gas at room temperature.
Nice analogy of ideal vs real
the creator of the knock knock jokes got the "no-bell" award
Van der Waals and Alfred Wallace were my favorite researchers
