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
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
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?
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.
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
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!
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. . .
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?
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.

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

Can you do one of the actual calculus and use of the equation instead of just an overview? Thanks! Great work!
Me -searching the whole world for a logical explanation and finds one at last .... thanks so much
how can you be me ??
Bless you so much!! I watched several different videos on this and didn't understand it until I got to you.
Can you plz explain why the area under the curve should be constant?
This has always been my favourite, the Maxwell-Boltzmann distribution, amazing!
Why i dont get anything 😢
bruh @@nimoosman7716
Really man you clearly are putting a lot of effort in making these videos. Respect++.
This guy is more mind blowing😂. Thanks, man. You're a life saver
7:52 so close
4:42 I think no. of molecules in system are constant right I am confused weather open system or closed one is discribed
How can you just perform the experiment on gas in open vessel
please make a video series on maxwell boltzmanns distribution function derivation.
what a blazing fast speed
420 LOL
Who’s doing AP chemistry and watching his video too👏
Some of us are engineers, and just peeking over the chemistry side because of FOMO.
I'm doing usual highschool chemistry
Last night before exam 💪
What about Masters in Physics and watching this 🤪
me 😢
Mind Blowing EXPLANATION...
Great explanation for laymen like me. Thanks for the upload.
Thank you so much sir you made this topic really interesting
Great, you made it easy to understand. Thanks!
ty so much u‘ve saved my life😂
lol u were so excited
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.
I highly appreciate for your nice explanation. Thanks a lot !
Hey Sal, please make a course on quantum mechanics
9:10 Are you saying that molecules in a medium have to be moving as fast as a wave propagating through the medium? Why?
What happens to the speed of sound at very low temperature then :0?
Gosh Sal Khan's videos are so dang good
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?
Can this distribution be applied on solid bodies?
Very well explained 😊
how did u get the speed of 422m/s? is there a certain calculation or was it a random value?
hey hii joelle FROM WHICH COUNTRY YOU BELONGS TO? as your name suggests you are may be from japan or koria or other country.
Nice explanation. Keep inspiring us!
Amazing Academy!
Those Nitrogen molecules are travelling faster than the speed of sound!
U make everything look easy.Thank you
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.
Excellent video! Many thanks.
I think speed of sound is less
because air particles moves in random direction but sound is measured only in some direction
Is it appropiate to say kinetic energy is proportional to average speed of the molecule or rms speed of the molecule confuz??
very well said
You are a great legend brooooo
thank you man fr helping me out
The y axis is not the number of particles. It is the distribution dN/dT. Please correct it.

You are doing a holy job 🙏
U r Amazing....
The best learning platform in the whole world = "Khan Academy". And guess what?...it's Freeeee....
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?
sir please explain how no of molecules change?
Wow such a great explanation
I wish they would teach us like this in school. Thank you khan academy
Buğra Kaan couldn’t agree more:)
Like to see opus of Maxwellians life and researching
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. . .
Can you make 2nd and third year courses as well
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?
Nope adiabetic compression approximates practical speed
the first HD video in the playlist, aleluia
love your work and love your voice
Why is the most probable speed the tallest point on the curve - shouldn't it be the highest speed instead?
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.
Such a great video
But why is container B narrower than container A?
can you please explain SMITH CHART ( Electrical engineering)?
Thank u a lot
😊💐💐💐
I love this thank you so much
Great👍
your graph is incorrect,the curves have to finish by approaching the x-axis asymptotically !
Well that's okay... Not a big deal.
im required to know this at GRADE 8😭😭 and my teacher cant do chemistry💀💀 thank you so much
Sweet ! that was so sweet
This was fun
Thanks a lot sir
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. 😐
Thanks 👍👍
An excellent video 👍🙌👌
awesome....👌👌👌👌👌
I still do not understand how the amount of molecules can change. Like isn't it supposed to stay constant?
What is this blackboard software?
Now how did we calculate the most probable speed?
differentiate it, the slope should be 0 at most probable speed
Why Maxwell Boltzmann distribution fell in quantum physic?
I came to watch this video for the same reason
Best !!!!!
I think in the graph x-axis is number of molecules n on Y-axis is speed, isn't it?
Someone please clarify me 🙏
yes
God bless you
Perfect!
Loved it!
That constant noise in my ear nowadays must mean something seen in this context don't you think? 😉
its been hotter nowadays, probably thats why lol
thanks :D
great
Why is his views so low guys do not take this lightly
Thank you :-)
jiashan1909
Wow😮😮
Thank you!!(=
How come particles aren't producing sonic booms all the time?
They are themselves the barrier
Super
even this youtube views have the same graph as maxwell's ditribution at 400 K
9:21 That voice break
your aware of it?
wow best
Consider your mind....
Boggled😎
God loves you all
waw
I tried catching a nitrogen right now...xd
👍👍👍
❤🎉
I’m now scared of nitrogen 🏃♂️
