This is a fantastic video. Very well done. I now understand much better where this constant came from. I am glad you took 8 minutes to explain it at the right level of detail.
Thanks for the nice video. Boltzmann's constant k is actually a repair action to rescale the Kelvin temperature to the kinetic energy of a particle that has the most probably speed. In fact, a particle in an ideal gas at equilibrium has with the most probable speed (vp) the kinetic energy: Ekin = kT = 1/2 m (vp)^2, where m is the mass of a gas molecule. Boltzmann's famous formula is the entropy formula: S=k ln W, where W is the probability (Wahrscheinlichkeit) to have a particle in a particular state (place & impuls). If the absolute temperature wasn't defined earlier on the Kelvin scale, we would probably have an energy scale. The entropy formula would have been defined as: S = ln W, and the associated kinetic energy Ekin = (1/2 m(vp)^2) = new temperature scale.
Found a video called Spacemind- Memory Hole. Saw a comment that said the picture in the background is of Ludwigs equation. Decided to look it up. Not into science that much or mathematics, however I am intrigued by knowledge in general. Edit: Tbh, I do not even know if this shit even correlates to my search lol.
Why did we have to do all the Boltzmanns constant stuff? Seemed logical to just put Na below R since we wanted the constant to take on an equal amount of smallness after the big N
The moment I was waiting for the explanation to begin, the video ends! 😞 What's that constant about? Why the pressure times the volume variation is linear with the molecules number times the temperature TIMES THIS NUMBER?
+Peter Solis but the Boltzmann constant is the energy of a single molecule at a particular temperature, is it not? So why not just add the "per molecule"?
Avogadro's constant has the value 6.022140857(74)×1023 mol−1 in the International System of Units (SI), not (molecule)/mol, same reasoning applies to boltzmann's constant. Molecules is not defined as a measurement within the SI system of values. It's just a matter of notation, if you want to use the correct SI units it would be J/K. It's just the standard way of writing it, I'm not saying that J/K(molecule) is wrong though, for the purposes of solving a problem it might be just as effective if not better. In this example he could of written the /molecule to lessen confusion, but he decided to just write it in standard SI which is just about the same thing.
+Peter Solis so it is not wrong of me to at least know in my mind that the Boltzmann constant corresponds to the kinetic energy of a single molecule at a certain temperature?

So, suppose I slap someone(not that I did), my hand has comparatively less speed compared to molecules, but it has a more mass and thus KE..., so will it cause the person I slapped to get warmer?
This is a fantastic video. Very well done. I now understand much better where this constant came from. I am glad you took 8 minutes to explain it at the right level of detail.
I got my confidence back after watching this video, well explained and all thanks to you
i love your way of explanation......
i love the simple words you use like "LITTLE N"..... god bless you bro
Fantastic video!! Absolutely! I learned in 10 minutes MORE R versus Kb than in ALL of Chnag's lousy textbook! Thank you for your superb presentation.
This was exactly what I needed in order to piece everything together, thanks!
Thanks for the nice video.
Boltzmann's constant k is actually a repair action to rescale the Kelvin temperature to the kinetic energy of a particle that has the most probably speed. In fact, a particle in an ideal gas at equilibrium has with the most probable speed (vp) the kinetic energy:
Ekin = kT = 1/2 m (vp)^2, where m is the mass of a gas molecule.
Boltzmann's famous formula is the entropy formula: S=k ln W, where W is the probability (Wahrscheinlichkeit) to have a particle in a particular state (place & impuls). If the absolute temperature wasn't defined earlier on the Kelvin scale, we would probably have an energy scale.
The entropy formula would have been defined as: S = ln W, and the associated kinetic energy Ekin = (1/2 m(vp)^2) = new temperature scale.
very well explained, thank you
매우 감사합니다. 한국어 자막 까지 있어서 진짜 도움 많이 됐어요.
very thanks from korea. It is helpful and especially korean subtitles are awesome!

Thankyou so much! This was an awesome video now i am able to understand what the concept actually is?
Very helpful, thank you!
Really very well explained 👏

Unfortunalely this does not give the microstates given by …….n!/n1!n2!...…..N!/n.
The moment I was waiting for the explanation to begin, the video ends! 😞 What's that constant about? Why the pressure times the volume variation is linear with the molecules number times the temperature TIMES THIS NUMBER?
Thanks, It was very clear...
Trying to understand this in your second language in 12:00 is hard af. But I have done it. Thx
So the Boltzman's constant is the necessary amount of energy to raise the temperature of an atom or a molecule by 1 Kelvin, right?
I get about these formulas but, to me they seem to have circular reasoning for the difficulty of where they got their measurements from.
Brilliant !!
Thank you so much sir
Thank you!
Very helpful. Thanks
Inconsitent: Left hand side of equation is PV=Pressure*volume = FORCE! Then, RHS of equation is ENERGY. The whole thing does not add from START.
Since p = F/A, therefore F = pA, not pV.
tq a lot
at last got wat I needed😊
thank you
Thanks 👍
Why is the unit of the boltzmann constant not written J/(K*Molecule)?
Good question , it should be , based on this video . I haven't checked scientific data to see the way it is notated but check online ?
number of molecules is just a number like number of apples, not really any SI unit
+Peter Solis but the Boltzmann constant is the energy of a single molecule at a particular temperature, is it not? So why not just add the "per molecule"?

amazing big thanks
do engines in hotter climate burn more oil or used more energy?
Oh my god- I remember why I don't watch the Khan academy any more... They seriously need to invest in better audio recording equipment.

Thankssss
8 minute for a division by Avogadro number? Shame on you.
((2.176470e-8 kg *(1.616229e-35 m)^2/(1.416808e+32 K *((5.39116e-44 s)^2) = (1.38064852e-23 m^2 kg s^-2 K^-1)
((Planck Mass *(Planck Length)^2/(Planck Temp *((Planck Time)^2) = (Bolzmanns Constant)
I thought n= N*NA? @4:00
better microphone?
It was fine for me. I suggest better headphones/speakers.
thank u sososososoaooaoaoaoaoaoasoossoosososossso much😊😊
Too much talk, not enough real info. You don't even talk about Boltzmann's constant until 3:25
Cool
👍👍👍👍👍

Your voice sounds like Eric Hovind's voice lol. But you know worlds more about science than he does.
Anyone who knows any amount of science knows infinitely more science than Eric Hovind.
david but no one can have infinite amount of energy
🍰🍰🍰🍰
He realized the world is made out of Spirit and that is basically what atoms and molecules are...
