My favorite thing about Hank is that he gets so excited about STUFF. He seems sometimes like that one kid in high school biology who loved learned about awesome stuff. That kid was always my favorite kid...He was also usually my best friend...
aaron silvera Further proof of the conspiracy, detective Silvera! Boyle didn't even come up with it, but it was he who got named after it. The ABCD gas laws... *It's a conspiracy.*
Dear Hank, Thank you so much! I have put off my AP Chem homework all summer because I've been busy all summer (Serving the homeless in MS for a month then a summer camp) So I was panicing, but you have managed to calm my nerves and help me! THANK YOU SO MUCH!
I am really impressed, I'll make sure to tell everyone I know who is learning chemistry (highschool of course) about these videos. Teachers teach this every year, the same stuff again and again, so often that they give up caring (mostly). You on the other hand, make one only video and really pack it with a punch, brilliant for everybody learning this for the first time. Honestly you are going to go down in history for one of the first people on youtube to aid equal learning opportunities for all
I love how the friendship between Michael and Hank is so obvious. I can only imagine there were a lot of outtakes of hysterical laughter during those scenes!
Omg one of the forest spirits from Princess Mononoke was at the birthday party! That makes me so happy lol. Incredible video crash course, I learn so much from your channel, keep it up Hank! -you too, lovely assistant who lives under the desk. Good job.
I REALLY ENJOY THESE VIDEOS! One time I dozing off on my course material over long drowsy calculations and the next I am laughing my head off at this awesome animated sci stuff!
@Shara: R has different values depending on the units you are using. Because Joules and calories are different and atmospheres, Torr, and Hg are all different, the value of R that you should use when dealing with gas equations depends entirely on what units your data is in (or you want it to be in, and change it to through dimensional analysis). Hope that helped!
For some reason I always imagined Michael Aronda was an older bald man lol. Crazy to think that I've been watching him on sci show this whole time lol. Great video btw!! Helped me way more than my chem professor! Thanks!!
He is Hank's best friend among strangers(it is John who is Hank's among family).I have best friends too among various places such as among extended family,among school and some animal friends among streets.
In high school I had a terrible chemistry teacher... Thank you Hank for proving that Chemistry is not only comprehensible but again that my high school chemistry teacher was terrible at his job.
Three years too late, but... Linguistics graduate here. It's actually even more confusing than that. He wasn't an English teacher. He was just an English teacher. /ˈɪŋ.ɡlɪʃ ˈtiː.tʃə / vs /.ɪŋ.ɡlɪʃ ˈtiː.tʃə / Stress - it matters!
I love how you show the camera the side of the tank that's clearly labeled with the volume it holds and then ask us not to comment on the exact volume of it.

Acetic acid is usually written CH3COOH, or more simply C2H4O2, but in this case, if you pause at 8:20, you will see that this is a acid/base reaction, where one of the H's in the acetic acid is being replaced with an Na, and C2H3O2 stays the same, so the way it is written does make sense.
something I never quite understood: If we imagine a closed container filled with 1 mol of a molecular gas and these molecules then split into 2 smaller molecules each, thus raising the number of gas particles from 1 to 2 moles - the ideal gas equation would suggest that the pressure of the whole system would increase. However: if we look at a single molecule it seems that the temperature must drop. One heavy molecule at speed x produces two lighter molecules which - due to conservation of momentum - should still have the same speed. but since their mass drops the average kinetic energy per particle (and thus temperature) should drop considerably. Also: while it is true that we do have more collisions at the same time due to the increased number of particles, the particles also got lighter by that amount. Is the solution simply that (excluding energy given to or taken out of the system due to the endothermic/exothermic nature of the reaction itself) temperature will drop and pressure stays constant?
You learned almost correctly. Water product can also be (g), as in combustion. I suspect that (s) is possible but rare. (ag) is never used with water. I think someone wanted to emphasis that the product water is in addition to the water already there.
Thank you for your awesome videos! They have been useful to me, ever since elementary school :-D Your videos, at that time, opened my eyes to the big and complicated world of science, and for that I am extremly grateful :-) Thank your for inspiring young people across the globe; to ask questions and learn more about "how it all works" :-)
Good video, but the analogy in the beginning could use a little more clarity. Do the kids and the adults use a single room (in the white house) or do they share both spaces (white house+ 5-year old's place)? In order to simply add the pressures to get the total pressure, the temperature and volume of the initial gases needs to be the same, and the final volume equal to the initial volume. Someone not familiar with Partial Pressures would not have made the distinction.
"Gas in scuba tanks is under pressure all the time." - I'd rephrase this to "Gas in scuba tanks has a high pressure." When something is "under" pressure, an outside force is being applied to it. Like if someone steps on your foot, your foot is under pressure. I suppose you could say that the tank is under pressure from the gas. Pressure is a property -a way to describe the behavior of particles.
I am a teacher and this is my first year teaching big kids.... as in eighth graders. After teaching kindergarten for 20 years, I have to take a huge test to show I am competent to teach science...they are eighth graders... Regardless, chemistry is not my strong point...ok the experiments are fun and we do a lot of those but we don't do the math... they are eighth graders...(btw they loved the video where the scientist gets his head chopped off.... they are eighth graders...) Long and short of it, thanks! I am lost on a few things but I am getting it. Enough to pass this test? Who knows....I don't believe in standardized tests anyway..... especially for eighth graders.
When you make the Carbon Dioxide with the reaction, there was already regular air in the bottle and the tube, so wouldn't it be Carbon Dioxide, water vapor and nitrogen and whatever else was in the regular air in the graduated cylinder? I don't understand how you can calculate for just water vapor and carbon dioxide. Were you simplifying things, or was there some way you didn't get any of the regular air in the graduated cylinder?

My favorite thing about Hank is that he gets so excited about STUFF. He seems sometimes like that one kid in high school biology who loved learned about awesome stuff. That kid was always my favorite kid...He was also usually my best friend...
For you to be able to explain Daltons law with such a level of simplicity, You're a GENIUS
Michael's expression when Hank says "exactly about" XD
hahaha
Well, he is not holding the graduated cylinder exactly vertical , he is holding it about vertical. Therefore the answer is in 'Exactly Abouts.' ;-)
ikr XD
I prefer to collect gas over mercury since its vapor pressure is about 1/8000th that of water.
Avogadro, Boyle, Charles and Dalton all came up with gas laws. ABCD. Coincidence? I think not.
Desmond Ong and edison
Boyle didn't come up with his gas law
Desmond Ong you forgot Henry
aaron silvera Further proof of the conspiracy, detective Silvera! Boyle didn't even come up with it, but it was he who got named after it. The ABCD gas laws...
*It's a conspiracy.*

Dear Hank,
Thank you so much! I have put off my AP Chem homework all summer because I've been busy all summer (Serving the homeless in MS for a month then a summer camp) So I was panicing, but you have managed to calm my nerves and help me! THANK YOU SO MUCH!
I am really impressed, I'll make sure to tell everyone I know who is learning chemistry (highschool of course) about these videos.
Teachers teach this every year, the same stuff again and again, so often that they give up caring (mostly). You on the other hand, make one only video and really pack it with a punch, brilliant for everybody learning this for the first time.
Honestly you are going to go down in history for one of the first people on youtube to aid equal learning opportunities for all
I love how the friendship between Michael and Hank is so obvious. I can only imagine there were a lot of outtakes of hysterical laughter during those scenes!
8:55 A wild Michael Aranda appears! I love Michael's face when Hank says "we have collected exactly... about..."
So.... is he always under the desk?
I think that's where he hosts sci-show from.
Don't you ever take a breath between sentences? Seriously though great stuff.
Lucas Campbell no. He doesn't, he breathes while he speaks.
The Cosmo Kramer painting on the wall in the background of the beginning animation made me smile :)
Can you believe it was 10 year's ago and still that beautifully explained with animation !!
i really struggled with the equations but this really broke it down for me! thank you so much! :)
+O isforOctopus : whos you kitty.....?...
Omg one of the forest spirits from Princess Mononoke was at the birthday party! That makes me so happy lol. Incredible video crash course, I learn so much from your channel, keep it up Hank!
-you too, lovely assistant who lives under the desk. Good job.
Thank you very much Hank, your explanation rocks!
I'm currently using it in research form thin film deposition parameters.
Michael's face when Hank says "we have exactly... about..."
0:28 I'm not sure if that's how five-year-olds dance, Hank.
hey listen what he say about partial pressure ,don't say useless things
*It's my party and I'll cry if I want to *
You would cry too, if it happened to you.
You like Melanie Martinez? Me too actually.
@@akemi-de-lol Nooo, its Leslie Gore. At least for me.
@@katerinacerna8555 Huh, which song was that? Cause I think I've heard of her before.
As for me the song is Pity Party by Melanie Martinez
@@akemi-de-lol "It's my party" a 60s song by Lesley Gore.
I REALLY ENJOY THESE VIDEOS! One time I dozing off on my course material over long drowsy calculations and the next I am laughing my head off at this awesome animated sci stuff!
That little grin that Hank did when Michael disappeared was unreasonably adorable.
@Shara: R has different values depending on the units you are using. Because Joules and calories are different and atmospheres, Torr, and Hg are all different, the value of R that you should use when dealing with gas equations depends entirely on what units your data is in (or you want it to be in, and change it to through dimensional analysis). Hope that helped!
For some reason I always imagined Michael Aronda was an older bald man lol. Crazy to think that I've been watching him on sci show this whole time lol. Great video btw!! Helped me way more than my chem professor! Thanks!!
He is Hank's best friend among strangers(it is John who is Hank's among family).I have best friends too among various places such as among extended family,among school and some animal friends among streets.
Michael's face when Hank said "exactly about" matched mine.
I enjoyed that.
As a future teacher i am not sure how much of this i will need for elementary school but i look forward to trying
This video is absolutely perfect for my high school chemistry syllabus! not too much not too little. Thank you, Hank!
0:30 0_o That party must have been... interesting
Once again, thank you Hank for helping me pass my Chem Lab Final =D
These videos are fantastic!! Thank you so much!
In high school I had a terrible chemistry teacher... Thank you Hank for proving that Chemistry is not only comprehensible but again that my high school chemistry teacher was terrible at his job.
Thank you SO MUCH for all the analogies and visuals!
He wasnt an English Teacher he was just an english teacher.
The E in the second « English » would be capitalized too since it’s his nationality. The only way to tell the difference is the context.
He was British.... oh I ruined the joke! Sorry!
Three years too late, but... Linguistics graduate here. It's actually even more confusing than that. He wasn't an English teacher. He was just an English teacher. /ˈɪŋ.ɡlɪʃ ˈtiː.tʃə / vs /.ɪŋ.ɡlɪʃ ˈtiː.tʃə / Stress - it matters!
I love how you show the camera the side of the tank that's clearly labeled with the volume it holds and then ask us not to comment on the exact volume of it.
When I first started, I had to rewatch some videos and thought I was dumb. So relieved to see other people doing the same thing!
You make chemestry so exciting! Really thanks for all your videos 😄😄😄
So happy to see Michael!
Thanks a lot. I thought it was much more complex. This helped.
This for sure isn't the first time someone has said it, but that intro... I love it :D
This should, be done hopefully for my ap Chem exam next year
OMG this series just got better. A+/10 trolling by the graphics department
Henry Reich is showing up more and more in Missoula stuff. I am getting more and more excited about this.
I'm in the UK (at uni) and we use both Acetic acid = common name, ethanoic acid = systematic name. Both are equally correct and usable.
Putting this one in my favorite
I'd like to think that Hank's lab assistant has always been crouched behind that desk, with that same smile on his face.
I'm making teachers to let us watch this in class... You're awesome
This entire series is just going whumph over my head
I feel so smart after understanding these videos
you just take my passion for science to a new level and i love you for that
I study chemistry. It's wonderfull, that you guys make it easier for many to understand. Thank you.
Can't wait to see what "Passing gasses" includes
More experiments in future videos! This one was great!
Also, at 9:20, the look on Michael's (sp?) face when Hank says "We have collected exactly... about..."
The way Hank says "BUBBLES" at 9:07, just magical.
This is the best vid of CrashCourse i have seen so far.. Loved it. It's hard to not learn with you! Thank you so much :D!

The ridiculous metaphors really are just fantastic(!).
I feel like im learning chemistry from capoose from red v blue... not complaining its awesome
Bubbles!
Acetic acid is usually written CH3COOH, or more simply C2H4O2, but in this case, if you pause at 8:20, you will see that this is a acid/base reaction, where one of the H's in the acetic acid is being replaced with an Na, and C2H3O2 stays the same, so the way it is written does make sense.
something I never quite understood: If we imagine a closed container filled with 1 mol of a molecular gas and these molecules then split into 2 smaller molecules each, thus raising the number of gas particles from 1 to 2 moles - the ideal gas equation would suggest that the pressure of the whole system would increase. However: if we look at a single molecule it seems that the temperature must drop. One heavy molecule at speed x produces two lighter molecules which - due to conservation of momentum - should still have the same speed. but since their mass drops the average kinetic energy per particle (and thus temperature) should drop considerably. Also: while it is true that we do have more collisions at the same time due to the increased number of particles, the particles also got lighter by that amount. Is the solution simply that (excluding energy given to or taken out of the system due to the endothermic/exothermic nature of the reaction itself) temperature will drop and pressure stays constant?

Michael's reaction when Hank says "exactly about" is perfect.
I'm finally understanding Chemistry....WOO!!!
Hey, i have a test on this tomorrow! Thanks hank!
That was funny when he appeared under his desk. 😂
thank you this was super helpful!!!
you said that twice
@@gabehowe ok got it thanks
Amazing video understood everything
I'm a fan of your speaking style
You learned almost correctly. Water product can also be (g), as in combustion. I suspect that (s) is possible but rare. (ag) is never used with water. I think someone wanted to emphasis that the product water is in addition to the water already there.
I sure do love cramming the day before the AP chem exam....
That analogy's great by the way !
I love the crash course animations.
Why did Voldy scar John Dalton's forehead, Hank?
rodaynah Voldemort did that
avijit dey I guess voldy is an abbreviation for Voldemort, Sherlock

Kramer painting in the white house..... love it!!
For AP Chem I recommend you listen to NMSI videos (look it up on google). I got a 5 because of them.
That analogy was amazing
Not bad! Making uni 1st year chem easy to understand :D
using a simple equation , we are able to calculate the amount of co2 produced in grams as well as moles . pretty impressive
Thank you very much Mr. Green.
"it's my party and i'll cry if I want to"- Gotta love hank
I like the reference to futurama in 1:15 The heads in a jar!
This would have been really helpful when I was taking Physical Chemistry a couple years ago... -.- It's a good refresher though.
Thanks for making this easy to understand!
Best thing I've ever seen.
Bouncing kids and adults. An elaborate analogy dealing with gas. 2:57 Dalton's Law Of Partial Pressures. 11:12 Summary.
Hank- "You can go away now"
*Michael casually, but slowly proceeds to crawl back down into his living space*
Is that a "Strange Charm" T-shirt? If so, I want one!!
Great video - especially the beginning.
Brilliant intro.
Thank you for your awesome videos! They have been useful to me, ever since elementary school :-D
Your videos, at that time, opened my eyes to the big and complicated world of science,
and for that I am extremly grateful :-) Thank your for inspiring young people across the globe; to ask questions and
learn more about "how it all works" :-)
Will Crash Course ever do a whole series on Quantum Mechanicssss
Good video, but the analogy in the beginning could use a little more clarity. Do the kids and the adults use a single room (in the white house) or do they share both spaces (white house+ 5-year old's place)? In order to simply add the pressures to get the total pressure, the temperature and volume of the initial gases needs to be the same, and the final volume equal to the initial volume. Someone not familiar with Partial Pressures would not have made the distinction.
How does he have an oxygen tank when he lives in Montanna?? That's where you live right?? I love your videos! Keep doing your thing!
"Gas in scuba tanks is under pressure all the time." - I'd rephrase this to "Gas in scuba tanks has a high pressure." When something is "under" pressure, an outside force is being applied to it. Like if someone steps on your foot, your foot is under pressure. I suppose you could say that the tank is under pressure from the gas.
Pressure is a property -a way to describe the behavior of particles.
I love these videos so much! They are going to help me "study" for my Chemistry Placement Exam! Thank you Hank! (:
I am a teacher and this is my first year teaching big kids.... as in eighth graders. After teaching kindergarten for 20 years, I have to take a huge test to show I am competent to teach science...they are eighth graders... Regardless, chemistry is not my strong point...ok the experiments are fun and we do a lot of those but we don't do the math... they are eighth graders...(btw they loved the video where the scientist gets his head chopped off.... they are eighth graders...) Long and short of it, thanks! I am lost on a few things but I am getting it. Enough to pass this test? Who knows....I don't believe in standardized tests anyway..... especially for eighth graders.
Tessa H Good luck dear!!! You'll do great i know it
haha the way zach popped up and "you can go away now":) all that creepy smiling
you have a very nice presentation HAHA j'adore. you make learning more interactive and interesting lol
That was probably the most tension-filled episode ever.
When you make the Carbon Dioxide with the reaction, there was already regular air in the bottle and the tube, so wouldn't it be Carbon Dioxide, water vapor and nitrogen and whatever else was in the regular air in the graduated cylinder? I don't understand how you can calculate for just water vapor and carbon dioxide. Were you simplifying things, or was there some way you didn't get any of the regular air in the graduated cylinder?
