The Maxwell-Boltzmann distribution | AP Chemistry | Khan Academy

[@grantbell8143]

You do the stunt work for high school and especially college students. Most professors blow over this thinking it’s obvious, but it’s not. And I thank you for that

[@shreehiwanj2935]

How does this this guy knows everything ( Almost Everything ) !!!! He not only knows things but also explains them in such lucid manner that even a 5th grader would fell it a piece of cake

[@Moneyisgoodforme]

"Why doesn't that hurt?" lmao I love Khan Academy

[@bakaiser0111]

Bless you so much!! I watched several different videos on this and didn't understand it until I got to you.

[@davidsweeney111]

This has always been my favourite, the Maxwell-Boltzmann distribution, amazing!

[@nimoosman7716]

Why i dont get anything 😢

[@MrPewPews]

bruh @@nimoosman7716

[@AhmedMustafax]

Can you do one of the actual calculus and use of the equation instead of just an overview? Thanks! Great work!

[@lydiajasmine6005]

Me -searching the whole world for a logical explanation and finds one at last .... thanks so much

[@georgen9755]

how can you be me ??

[@kaustavmukherjee8844]

Really man you clearly are putting a lot of effort in making these videos. Respect++.

[@siuuu0776hv]

Mind Blowing EXPLANATION...

[@Pooja-ll9sl]

This guy is more mind blowing😂. Thanks, man. You're a life saver

[@jessicadu6103]

Who’s doing AP chemistry and watching his video too👏

[@777Skeptic]

Some of us are engineers, and just peeking over the chemistry side because of FOMO.

[@a.syndeed]

I'm doing usual highschool chemistry

[@bidyutdatta7464]

Last night before exam 💪

[@davel7037]

What about Masters in Physics and watching this 🤪

[@dub22]

me 😢

[@silkederouck9107]

Thank you so much for explaining the graph!

[@jokerwierd6454]

7:52 so close

[@jaraxel888]

Great, you made it easy to understand. Thanks!

[@tonysuffolk]

Great explanation for laymen like me. Thanks for the upload.

[@anubhavshankhwar]

Can you plz explain why the area under the curve should be constant?

[@scigy]

what a blazing fast speed

[@DogeFrom2014]

420 LOL

[@idkwhattfiamdoing5653]

Very well explained 😊

[@Frostbitecgi]

please make a video series on maxwell boltzmanns distribution function derivation.

[@asharbuland3193]

Mind boggling as he said!

[@parthkhanayat420]

Thank you so much sir you made this topic really interesting

[@Abhi-mu2cy]

4:42 I think no. of molecules in system are constant right I am confused weather open system or closed one is discribed

[@Sad_Atma]

How can you just perform the experiment on gas in open vessel

[@anotherdayofpreventingtrav8513]

ty so much u‘ve saved my life😂

[@sharifulislam-tj2dy]

I highly appreciate for your nice explanation. Thanks a lot !

[@Cosmin-IonutFlorea]

Can this distribution be applied on solid bodies?

[@rodolfogrosso5180]

Excellent video! Many thanks.

[@sciencenerd7639]

Gosh Sal Khan's videos are so dang good

[@boogychan]

The best learning platform in the whole world = "Khan Academy". And guess what?...it's Freeeee....

[@ManuArtoneforall]

Amazing Academy!

[@tokajileo5928]

I just learned from aother online class from Reginald Penner that this maxwell boltzmann distribution is not the description of all states but the whole distribution is showing only the most probable state, so this curve is not the whole reality but the most probable one. There is a misunderstanding that this curve describes everything in a system but not, just the most probable case, I mean not one point of it or the maximum of it but the whole curve!

[@raghavendra007kinder8]

thank you man fr helping me out

[@A4bandz]

lol u were so excited

[@raanoooshh9296]

Well, some of the molecules were indeed in the first EXCITED state ;)He acted with them so we get a feel about the Maxwell-Boltzmann Distribution.

[@apwned]

I wish they would teach us like this in school. Thank you khan academy

[@microhoarray]

Buğra Kaan couldn’t agree more:)

[@mohamedmusthafa814]

Nice explanation. Keep inspiring us!

[@hershyfishman2929]

9:10 Are you saying that molecules in a medium have to be moving as fast as a wave propagating through the medium? Why?

[@jasirmukhtar2162]

U make everything look easy.Thank you

[@pollockshaun]

Hey Sal, please make a course on quantum mechanics

[@riturajsinghpanwar6470]

You are doing a holy job 🙏

[@himanshuthakur883]

You are a great legend brooooo

[@Abhi-mu2cy]

I think speed of sound is less because air particles moves in random direction but sound is measured only in some direction

[@Damn-Age]

What about the temperature of a vacuum system? How do we set the framework to analyze that? I am sure we will then be talking about even smaller particles like the photon. Do we have a video covering that?

[@CanbarSom]

very well said

[@squaresensei]

Those Nitrogen molecules are travelling faster than the speed of sound!

[@ShweMi-g7l]

Even the dog back then looks like a scientist

[@Midnight-xc3vc]

Wow such a great explanation

[@FPSvolter]

the first HD video in the playlist, aleluia

[@ubwvww1]

U r Amazing....

[@ryklin1]

This seems over simplified. What you described are just Gaussian distributions of various particle speeds, emphasizing how the sigmas and means change as functions of speeds; perceived as different temperatures. I'd like to learn more. I suppose that a given particle changes its speed over time.

[@itdoomkiller]

im required to know this at GRADE 8😭😭 and my teacher cant do chemistry💀💀 thank you so much

[@loveisphysicsy9679]

An excellent video 👍🙌👌

[@person17_ro]

Such a great video

[@oonievlogs]

how did u get the speed of 422m/s? is there a certain calculation or was it a random value?

[@QueenTanu24]

hey hii joelle FROM WHICH COUNTRY YOU BELONGS TO? as your name suggests you are may be from japan or koria or other country.

[@saaadmm1732]

Thank u a lot 😊💐💐💐

[@ishanp7484]

sir please explain how no of molecules change?

[@actionrazorthecut9161]

Sweet ! that was so sweet

[@mayukhbasak7449]

awesome....👌👌👌👌👌

[@littlethings4172]

Great👍

[@malekemerald9948]

love your work and love your voice

[@dieterecke5083]

What happens to the speed of sound at very low temperature then :0?

[@priyamvadapriyam9415]

Thanks 👍👍

[@tristanmoller9498]

I love this thank you so much

[@themechanic5628]

The y axis is not the number of particles. It is the distribution dN/dT. Please correct it.

[@Dai_rui]

Can you make 2nd and third year courses as well

[@zoubiaateeq8747]

This was fun

[@usman5954]

Perfect! Loved it!

[@ANJA-mj1to]

Like to see opus of Maxwellians life and researching

[@i.m.Q.2]

This is great except for one small detail. Going through all of that and I still don't have the most important thing-the actual equation. 😐

[@RemunJ66]

That constant noise in my ear nowadays must mean something seen in this context don't you think? 😉

[@tejasshenoy2095]

its been hotter nowadays, probably thats why lol

[@mr.rathore7051]

Thanks a lot sir

[@dhairyaparikh3048]

Absolutely amazing explanation, but I am wondering how can a particle or air i.e. nitrogen have a most probable speed greater than speed of sound ? seems weird

[@kidamaroo]

The speed thing that he mentions sort of reminds me of the speed on sound. Is there a relationship between the Boltzmann Maxwell distribution and the speed of sound?

[@eusterich3035]

Nope adiabetic compression approximates practical speed

[@emirselman3984]

Why is the most probable speed the tallest point on the curve - shouldn't it be the highest speed instead?

[@unFayemous]

Emir Selman no, because having the highest probability means the highest amount of particles will have this speed (as compared to other speeds). Since the Y axis describes the amount of particles that should have that speed, the most probable speed will have the largest amount of particles, thus have the highest Y value.

[@tristanmoller9498]

Now how did we calculate the most probable speed?

[@林潮篁]

differentiate it, the slope should be 0 at most probable speed

[@bishalthapa4639]

Is it appropiate to say kinetic energy is proportional to average speed of the molecule or rms speed of the molecule confuz??

[@leiashen7008]

But why is container B narrower than container A?

[@axilles2023]

your graph is incorrect,the curves have to finish by approaching the x-axis asymptotically !

[@akarshanpandey7036]

Well that's okay... Not a big deal.

[@gerhardbritz1196]

I still do not understand how the amount of molecules can change. Like isn't it supposed to stay constant?

[@person17_ro]

Best !!!!!

[@jiashan1909]

Thank you :-)

[@royfernando860]

jiashan1909

[@furmankhann]

can you please explain SMITH CHART ( Electrical engineering)?

[@jastu1526]

9:21 That voice break

[@CanbarSom]

your aware of it?

[@stokey99]

how is the left axis number of molecules,, and if it is, how can the number of molecules just change in a system?? i don't understand?

[@canys24bb78]

Why Maxwell Boltzmann distribution fell in quantum physic?

[@JKBEAST]

I came to watch this video for the same reason

[@basmahussein5453]

Wow😮😮

[@denkenunddanken5961]

I think in the graph x-axis is number of molecules n on Y-axis is speed, isn't it? Someone please clarify me 🙏

[@megamik1993]

yes

[@sologouda6180]

God bless you

[@henrikwong9545]

What is this blackboard software?

[@khyatisingh747]

How does having the same area equal the same no. Of molecules each container has. Won't area be like, fraction of molecules×Vel. ??? How does it give us no. Of molecules?? Can someone kindly explain. . .

[@tomduke558]

that thing is beyond their time.. why they wont just wait 200 years

[@saniynazeer3152]

Why is his views so low guys do not take this lightly

[@Hell123o]

I tried catching a nitrogen right now...xd

[@hamzaamdii6018]

thanks :D

[@osnatcsillag8596]

Thank you!!(=

[@Pavan_Gaonkar_abc]

even this youtube views have the same graph as maxwell's ditribution at 400 K

[@KookinHaole]

How come particles aren't producing sonic booms all the time?

[@ricardoraimundo4762]

They are themselves the barrier

[@aliyajamal3757]

great

[@ak02.9]

I’m now scared of nitrogen 🏃‍♂️

[@govindraju2934]

Super

[@mamioroyoutube5111]

wow best
