This professor today has became a Nobel laureate in chemistry
And a climate change wacko.
@@YesYou-zy7kp you surely understand better climate change than a professor of thermodynamics and chemistry nobel prize winner..
@@asdfafafdasfasdfs You mean a Nobel Prize winner AND a leftist stooge? They are not necessarily mutually exclusive.
@iamgoodperson484I'm in 8th
@Mathematics01632well they're channel was made 11 years ago.
Congratulations Prof. Bawendi! I've been watching your videos here since 2009. I can't believe you're a Nobel Prize Laureate now! 👏
This professor just simplified and made me understand everything my professor is teaching me for the past 2 months of thermo class. His global story in the beginning was actually to help students understand the difference between macro and microscopic properties of thermodynamics. If you follow exactly what he is saying, it should make sense since he actually defines everything-which ALMOST every thermo professor will not do. Count yourselves blessed MIT students. And thank you for sharing!
He just won nobel prize
I love how intuitively he explains thermodynamics. this man is an incredibly gifted lecturer
an incredibly gifted lecturer.... will never take a scrap of paper to make a lecture out of it ...Richard Feynman was a gifted lecturer ... moderation is required in your judgement especially if the number of gifted teachers that you have ever seen equals to zero /// his way of providing this lecture by reading from the paper plus his internal state of great anxiety looks like ////well just for polite correctness I won't go any further
@@alexsheremett3097 Did you just reply on 7 years old comment praising the teacher, just to insult him? wow, thats something else
@@RomanUrbanek first I didn't insult read carefully what I wrote second... He insulted himself by reading from a scrap of paper third about the content bad incomprehensible.. You can pick up more by reading Wikipedia.. Four you can't even imagine how far... Like English and Chinese language....I'm from thermodynamics... But I needed urgently to brush up on the topic ... And the lecture was catastrophic... Now five what the hell has to do that s 7 years old by the way I didn't look the date... It was bad. . Best regards over..
@@alexsheremett3097
I'm sure negative review of a teacher from the best engineering school in the world, comming from nobody on youtuve has value.. to someone :)
@@alexsheremett3097 who cares if he's orienting from notes? I didn't even pay attention to that until I read your comment.
Thanks MIT for upload all these excellent classes. I'd like to make a donation but I'm just a poor engineering student...
I was just wondering. Is this calculus-based?
German Pedro
there is the heat equation. I actually have no idea how to use such a differential equation.
welcome to the broke club !
@@srpenguinbr read Atkins or puri sharma.... Your concepts will be cleared
I saw his picture as Nobel winner and I quickly recognised that I had listened his lectures on Thermodynamics few years back. Today I came here to reconfirm. Heartiest Congratulations❤
I'm going to watch all of these before my winter course starts. The professor in this video is excellent at explaining the material. Thank you MIT.
im doing the same, how was your experience?
Me too I'm a greek mechanical engineer
Guys, I found these lectures very helpful. Can anyone of you tell me that which book is Sir following?
@@yasirkhan1396 weber is a good one
@@lel3923 I went to Maryland and our course was very fast-paced, literally a problem set due every day. Even though I got an A in the class, I would only recommend a winter class as a last resort. I also didn't make it past the first video lol.
I must say, Its been a long time since I heard and saw a professor that describes a subject so well. Clear spoken, good comparisons and takes his time. Great lecture!!

I respect MIT, their Chemical Engineering Department. All the related open course presentations I've viewed are excellent, efficient to focus on the significant examples, theories, conclusions.
Aploading these videos is GREAT not only for students but for general knowledge as well. I actually enjoy watching such videos as i enjoy watching scientific documentaries. I took thermodynamics in college a long time ago and I still come back to it from time to time through these videos. Thank you MIT and I hope to see more universities follow suit.
They just launched a new version of this course (by a different prof) on Edx. Check out: MITx: 5.601x Chemical Thermodynamics I: Thermodynamics and Statistical Mechanics
Watch it one time and you keep everything in your mind forever. Thats how good it is!
This is soooo good. I can't put in words how much I appreciate these MIT courses. Altough I'm from Germany the course is pretty much the same and the lecturer is soooooo good, mine is so hard to understand that it made physical chemistry look boring, but now I seriously can't stop watching these lectures. This is the greatest thing UA-cam and the MIT offer, for free!
Amela Mesinovic almost all of the lecturers are very charismatic.. it might be a prerequisute to teach there! At our university (also in germany) we have environmental science lecturers that are so boring they actually lose significant parts of their audience after a few weeks in every semester. So yeah very good there are such courses offered online.
You should check out their chemistry course too.! The professor there is outstanding.
What a great time to be alive. A full course from MIT on thermodynamics; complete and free.
This professor is amazing kept me engaged on viewing this and I usually get easily distracted and I loved he put in parts of the history of thermodynamics. I hope he is still making lecture videos and teaching.

@@enisten Thqnk you so much I'll definitely check it out :)
Surprising how much this is helpful to Philosophical topics in one lecture than a whole week or semester of philosophy lectures.
Such a charismatic lecturer. He makes it 100% easy to UNDERSTAND!
I loved thermodynamics from these lectures, you made it simple, congratulations prof on your noble prize
Hi Physics student here, just have to say I've gotten thorough enjoyment over your argument with Mr. Williams. I actually did a paper last semester on alternative fuel/ eliminating use of fossil fuels. I'm always fascinated by peoples' stands on oil and alternative/ renewable energy.
I love the way he teaches. After teaching for some time he asks whether students have any question or queries in their mind.
The Ocean Conveyer and Evaporation/precipitation cycle are natures example
The Sun heats the Tropical waters, Deep Space super cools the Polar waters, hot water rises,cold water falls the result is the Ocean Conveyer that uses the difference between hot water and cold water to create Kinetic motion(repeat)
As heat from the Ocean rises it created moist thermals, hot air rises, cold air falls and the difference makes wind by kenetics, as heat disapates it makes Clouds that rain(repeat)
It's 3 a clock in the morning and i'm watching this. The teatcher explains this subject so good that the time doesn't matter. I had previously experiences with Thermodynamics and it not worked as good as i wanted to be, maybe because the professor didn't make the subject interresting, or maybe because i was unable to understand that in that time.
All of this to say thank you, and express my profound hapiness of learning (reviewing) so many things with this video. Thank you so much :)
i'm glad that this has subtitles... my native language isn't english but i love to listen to it :) Great explanations but... what a quiet class .-.
That is a college class. You are not supposed to talk
sameee
@@crazychimp1039 biggest lie. I think Barb meant like no one is asking questions.
I love all the videos that MIT offers like this. thank you guys for putting this stuff out there for other people to have the chance to open up their minds to newer, bigger and better ideas.
A very brief introduction to PHYSICAL CHEMISTRY. Thermodynamics and Chemical Kinetics are 2 branches of Physical Chemistry.
There is a lot of blather below regarding whether the lecturer, who is excellent, made a slight mis-statement of this point or that point. All of which is beside the point. What I learned from 5 years of work towards a PhD in physical chemistry is that once through the material is never enough. It takes a combination of live lectures, several textbooks, study guides, writing out mathematical derivations until you understand them, and endless problem solving.
This instructor teaches in a very easy to understand coherent way. His eyebrows are the focal point of his face.
Summary
Laws of thermodynamics
From i to f both are equilibrium
Infinity of way to move from i to f
P=f(V); isobar isothetmal ...
2 types of system: homologous. Heterogeneous
3 nature of system; open (mass and energy) close (no mass only energy) isolated (no mass no energy )
States described only in i and f despite work W and heat flux Q (W&Q describe way)
Function of interpolation: linear .. quadratic
By breaking even he means energy is conserved in an isolated system. If you have 50 J of potential energy (U), that 50 J's of U can be converted into kinetic energy; problem is some energy will be lost due to friction. The energy that you do lose is forever lost to the universe. Hence, if you can reach absolute zero temperature (0K), you prevent the loss of energy due to friction. This is what he means by the 3rd law (you can never break even). Absolute zero can never be achieved.
Watching these videos is a great way to pass out when you're trying to sleep at night. Not that his lecture is particularly boring, just any lecture is boring.
this is the best ever thermometer explanation
Congratulations on your Nobel prize in chemistry
Yes. It's similar to first-semester Physical Chemistry in most universities. Requires 2 semsters of Physics w/ Calc, 2 Semesters of Gen Chem, Single & Multi-Var Calculus, Diff Eqns (ODE), and Organic 1 & 2 is strongly recommended.
Is this usually in the 2nd or 3rd year ?
@Tanjiskas it means that you convert 100% of the heat you are inducing into the system into useful work. which means that the efficiency is 100%. actually the first never said that but it just didn't mind it. so the second law said that you cannot reach 100% efficiency because you are always generating entropy along the way and by increase in entropy you are wasting energy
Best teacher in my experience so far.
Congrats professor for the Nobel and thank you for your contribution in science.
I wish we had him as our prof.
I was amazed that this was physical chemistry course. And here, we don't have even 10% quality lecture in engineering thermo class..
Nobel laureate in chemistry 2023
I was born when this lecture was uploaded and now im preparing for my test through this 👍🏻
Entropy
Henry Poincare named the conception of "entropy "
as a " surprising abstract "
Lev Landau wrote:
" A question about the physical basis of the
entropy monotonous increasing law remains open "
One physicist said :
" The entropy is only a shadow of energy“
#
History of Entropy
1 - Clausius : dS= dQ / T.
2 - Boltzmann : S= k log W
3 - Planck : h*f = kT logW
#
The formula of Entropy is : h*f = kT logW
Israel Sadovnik Socratus
He means that the 2nd law defines the direction of spontaneous change. A process is spontaneous only if the total entropy of the system in which it occurs increases. For example, sugar dissolving in hot coffee occurs spontaneously -- sugar will only crystallize from hot coffee if energy is expended. i.e. the entropy of the universe must always increase--it follows the direction of natural change, a.k.a. the "arrow of time". The 2nd law is also about the reversibility of change No more room!
In India, coaching institutions are charging thousands to offer such lectures . Thank you, MIT
I really like the way he teaches
Summary
Laws of thermodynamics
Studying the way of states from i equilibrium to f equilibrium
Despite work W and heat flux Q
To describe one system just need to know : n nombre of moles and 2 variables
Infinity of the way from i to f
We need to justify if the system is Thermodynamiclly equilibrium or not
Function of form : interpolation linear, quadratic...
Measuring of temperature scales
this video might help too
Thermodynamics 1st Law (Thermal Decomposition)
I feel so blessed to see these lectures .This is helping me so much in school .Lots of love from Albania 😁
What a gifted lecturer. I just realised I misunderstood and overcomplicated thermodynamics in my undergrad.
They just launched a new version of this course (taught by a different prof) on Edx. Check out MITx: 5.601x Chemical Thermodynamics I: Thermodynamics and Statistical Mechanics (course 1 of 2)
How does these full lectures compared to the Edx ones?
Congratulations Sir..👍🌹🙏
Thanks for actually teaching and not just being a robot. If only other instructors new how to teach. While filling out my FAFSA, I noticed Wright State only had a 38% graduation rate.
42:07 this thing happened to me a lot, so i stopped asking questions in the class. Don't be like me.
i caught that he spends a good deal of time looking down when he's thinking you can tell its habitual. he fails to mention that the American standard has historically changed over time by small increments if he was going to bring up the Dr. in lecture it a small cite to mention that better explains why we see what we do today.
Sir I am still in high school ,can I see these videos?
thanks, greetings from México:)
The macroscopic view is ruled by conservation and microscopic view was initiation or seeding rain or seeding wind for example
pinned neutron superfluid provides an angular momentum reservoir as its rotation rate is determined by the areal vortex density, which is constant as long as it is pinned to the crust. At the same time, the crust continuously slows down due to loss of its angular momentum in the particle wind and electromagnetic radiation. At a critical lag in this differentially rotating two- component system, superfluid vortices get unpinned, dumping a large amount of angular momentum to the crust, which is observed as a spin-up in the crustal rotation rate, usually inferred by timing the radio pulse (Alpar et al. 1984a, 1985). This implies that the fractional spin-up provides a probe of the extent of angular momentum transfer and hence the MoI of the crustal pinned superfluid. The ratio of the MoI of the crustal pinned superfluid to that of the rest of the star, referred to as the fractional moment of inertia (FMI), can be related to the observed fractional spin-up
Equal volume ratio liquids do not imply equal molar ratio. (In case you have not learned, liquids are pretty damn far from ideal gasses; water is denser and has a lower molecular weight than ethanol, equal volume ratio means much higher molar ratio of water to ethanol)
I recommend you reading your high school chemistry notes again.
Thanksyou MIT, with this I could start preparing for my next semester
Thanks MIT,all the way from South Africa...:)
Thanks for uploading.. that made thermodynamics much better for me...
Thanks MIT for uplaoding this gem. This is just fabulous kindly upload solid state mechanics
They just launched a new version of this course (taught by a different prof) on Edx. Check out MITx: 5.601x Chemical Thermodynamics I: Thermodynamics and Statistical Mechanics (course 1 of 2)
thank you, the lecture helps a lot. This course is so stressing.
because in order to get absolute zero, you would need to remove all the heat and since heat transfer in a preferred direction from high to low, theoretically you would need something less then absolute zero to remove the heat.
Love it when he starts talking about Fahrenheit scale
That's a nice cook, as expected from MIT.
@Polyfusia Yes, I guess I misunderstood you. In that case, I would re-study all of the material on my own time.
In most math classes I would not understand the lectures, and so studied all of the material again in the textbook when I got home.
Look, I'm not saying that it's your fault or whatever, but if you want the education, you find a way to get it. It's not as if having excuses about why you can't do it will help you in any way.
We have to learn (actually remember) all that stuff in grade 11. Thank you very much for explaining everything in detail.
How was your jee?
How did you do?
Thermodynamics inside a expanding multiverses. We are inside a blackhole, when event horizon get open, how it's looks than with the thermodynamics in a multiversians model. Thematic, Magnetic Pepeetum Mobile, Blackholebomb Pepeetum Mobile and so on.
Great lecture ! Really enjoy this topic and the way our prof teaches too.It helps me understand more deeply and cleary. ( as a student of École Polytechnique )

Heating is the transfer of energy. It is not a substance therefore cannot "flow". If it could flow it would "flow" in any direction, but heat is only transferred from warmer to cooler and cannot be reversed.
God bless this channel!
what a relief..what a real relief..i always feared thermodynamics confused like a shitt..but man this lecture series helps a lot!!!
Great lecture. Uses lots of examples and makes it easy to understand.
There technically is no such thing as an isolated system. It's just a useful basic "fudge." I'm sure the genius MIT professor knows this, he's just making things simple for introductory students. Given sufficient time, the contents of even the most robustly insulated container will reach equilibrium with the surroundings.
Good for you, you'll have a blast! I'm taking the equivalent of this thermo course now - for me it is called physical chemistry - and let me tell you, it is *really* challenging!
thanks here sir and complete team for being arrogant with who challenge humankind survival ,life is challenging and difficult thus we thanks our mentor who help us in enjoying the same ....
Just came to say that on the thumbnail the teacher is PERFECTLY camouflaged. Nice.
This is how engineering should be tought. Reading off slides like it's done today is just pointless. I can do that myself.
35:02 very good question. Boundary between reversible or irreversible.
I love how he starts explaining the thermodynamics of 100-proof vodka with a complete straight face as though it's no different from CO2 or H2SO4
oh my god I'm taking 5.60 next semester I'm so glad this is here now I never have to go to lecture
I know many of you don't care about this, but the translation of the captions is pretty fucking good, at least for spanish. I'm actually impressed about it, a great applause to the google developers.
Interesting lectures,pure science definitions...Am enjoying this lectures.
First course looks promising. 2 questions: a) at 17:20 is there any reason why he does not add "S" to the variables that describe the state ? b) Will there be some problem sets that go along with the lecture ?
I hope you found your answer by now lol
This is a very valuable resource...
Fantastic professor and his way of teaching is easy to grasp for a beginner!
amazing first lecture on macroscopic thermodynamics, expected nothing less from MIT kudos
thermo in greek does mean heat but here it is mainly considered as energy since thermodynamics deals with work and heat interactions
Excellent lecture. I find Thermodynamics an inherently dull, unexciting subject and thus difficult to teach but this is lecturer is SO engaging I'm reallly enjoying it! Surprise surprise...
Can anyone recommend a good book? I'm using F.Mandl's Statistical Physics and it's a chore to read... Bland prose.... little, vague or irrelevant examples for unclear end of chapter problems... If anyone has had any luck with a book on Thermodynamics for 2nd year Physics it would really help!
Thanks MIT for upload this video
so lucky to be taught by a Nobel prize winner
Life is the result of action of laws of hierarchical thermodynamics.
@kayanathera I think he has on that paper the lesson plan NOT the basic concepts!
Because if he hadn't known the basic concepts he wouldn't have been able to explain them so good!
You might notice that the common word "heat" is used as though we already know what it means. The lecturer does not define it. But if you look up "heat" in Wikipedia you might be surprised, as I was, to find that the definition is not obvious:
"In thermodynamics, heat is energy in transfer [...] by mechanisms other than thermodynamic work or transfer of matter."
Note the word "energy." Reading further in that same Wikipedia article:
"As a form of energy, heat has the unit joule (J) [...] The standard unit for the rate of heat transferred is the watt (W), defined as one joule per second."
So, according to the content of the lecture plus the content of Wikipedia, energy moves from a hot body to a colder body. The rate (per second) of energy transfer can be measured in watts. The total energy transferred can be measured in joules, or (as we know from looking at our electricity bill) maybe even in watt hours.
Heat is energy. I personally do not find that obvious.
These are MIT students.
@@iridiumdx6682 Your point?
@@RalphDratman My point being that this is a lecture for MIT students which happen to be publicised for public use. At least someone taking this should be familiar with the concept of heat as energy. Such trivial thing does not be reinstated in college, let alone at MIT.
12:00
Where there's a thermodynamics.... There's a hot 🔥 coffee ☕😃😃😄😄😄😄
Amazing relationship
6:09 that piece of chalk IS time. time is 3 dimensional. Except the 3 dimensions exist in a reciprocal sector, and we see only the 1 dimension in our sector. For truth's sake, read Dewey Larson. It is the unified theory. Do it.
35 years ago I heard the same story about “smart” people coming up with ideas to circumvent the “Second Law of Thermodynamics” from my Thermodynamics professor. Apparently things haven’t changed that much since then. I was assuming “progress” of humanity that turned out to be a fallacy.
I wish I had found these before my second semester started
Thermal is related to photons therefore our focus should be on photons. Changes in the saturation of dynamic photons within a system would lead to changes in temperatures either due to the presence of a heat source or heat absorber. Precisely temperature should be defined as the availability of dynamic photons per volume per time within a system.If there is a heat source, it would be flooded the system with abundant of dynamic photons and the effect would be to raise the temperatures within a system. On the other hand, if there is a heat absorber where heat (dynamic photons) would be sucked away would cause drop in temperatures. Atoms are constantly exchanging photons with the surroundings in which both nucleus and stationary electrons of an atom would stockpile dynamic photons from the surroundings before transforming them to stationary photons in which at the same time some stationary photons from the nucleus and stationary electrons of an atom would be released as dynamic photons to the surroundings. If the atom only gained more and more stationary photons than the ones that it dissipating to the surroundings due to high availability of dynamic photons within the system, the atom would increase its kinetic energy per time in which it would increase its vibration rates, or increase its transverse velocities, or both. Therefore changes in temperatures would lead to changes to the kinetic energy of atoms within a system.Total energy of a "system" (the entire universe) would always be the same. It is wrong to say the energy tends to move from high energy to low energy while entropy, S, moves from order to disorder. The total energy of the entire universe is always be the same. The universe is always there as per the law of conservation of matter. Einstein's famous equation, E=mc^2 is wrong otherwise garbage also can be used to make atomic bombs as long as it is matter or it has mass. We know this is not true. Energy and matter cannot interchange one another according to Einstein's famous equation. One must have photons before one can emit out photons. Photons are particles and they have mass. Dynamic photons possess momentum.The universe would expand to its maximum size before implosion and the final stage of implosion would be Big Bang where all celestial bodies would be flung outwardly to facilitate for expansion. NASA claimed that we can see the formative state of the young universe which clearly attests that all celestial bodies were travelling much faster than the speed of light in the past but somehow they have slowed down for quite sometime already slow enough now to allow the light of the past to catch up with us now to allow us to see the young universe. Imagine the celestial bodies would accelerate towards the center of the universe for billions of years where their speeds should be several times faster than the speed of light before they reaching the center of the universe; therefore the impacts of Big Bang is beyond our imagination. When celestial bodies been flung out from the center of the universe, their speed would also be several times faster than the speed of light. Therefore it is wrong to say that entropy moves from order to disorder. Thermodynamic should be the studies of photons. In God I trust.
the universe and with some limits to how large u want your system to be within that universe is technically a isolated system
"K" used to be called "degrees Kelvin." With the adoption of SI, they dropped the "degrees" part, so you simply say, or write "K," not "degrees K." But they are still degrees--of the same "size" as C degrees, but starting out at absolute zero.
Thank you MIT for these video lectures
Why should the thermos can be an isolated system? Energy is leaving it, as the system comes (slowly, it's true) in equilibrium with it's surroundings (outside temperature). I posit it's a closed system, like the water with ice cubes in it.
