I've been doing thermodynamics in some way, shape or form for three years now and this has been by far the best presentation for these concepts that I've come across. Thanks Dr. Shini. Lecturers could literally spend two days explaining what she did in ten minutes in class. You guys are awesome.
Physics is so interesting when you actually get to know and understand it, I really want to sue all my school teachers for not doing their jobs correctly and for only scraping the surface when it comes to Physics, it really is just so frustrating when you are so interesting in something that you can't even understand properly
This is so helpful! We've been doing thermodynamics as uni but I tend to sit in letcures with my eyes glazed over because I didn't fully understand the basics when we first learned them, so anything more complicated is too confusing.....
The other videos aren't as fast and hard to keep up with. There is of course an effective way to give Crash Courses, and this series presenter doesn't demonstrate that unfortunately.
First law of thermodynamics: You don't talk about thermodynamics. Second law of thermodynamics: You don't talk about thermodynamics. Third law of thermodynamics: Who's new sweats.
I love physics but my school's program sucks (I get 120 minutes a week), there is no extracurricular options to learn more physics and I can't afford private classes. I want to become an engieneer someday and your videos are keeping that dream alive, thank you!
watching this after 7 years of it's release, she still explains it better than my teacher. and i even got a thermodynamics test tomorrow and this is just an absolute lifesaver.
Lovely explanation. Although if I was a student cramming for an exam, I would watch this video at 3/4 speed. You surely can talk fast Ms. Shini ( or Doctor Shini I would assume).
Other question- in the isobaric process example, it seems like the gas cooled when the piston was pushed down. I understand that in the equation, a temperature decrease would balance a decrease in the volume of the container. But, by what mechanism does this happen? I can't figure out *how* decreasing the volume would cause the gas to cool. It seems to me like if anything, doing that would actually cause the molecules to move even faster, although to an imperceptible amount. And after all, as she said, we're doing work on the system, so unless there's an exit for heat, wouldn't the internal energy increase? Would pushing the piston down not just raise the pressure of the gas in an inverse ratio to keep the left-hand side of the equation of equal value?
I'm not one to comment often, but man I get so excited when I see these videos in my news feed. I can't get enough of them. And I'm an upcoming mechanical engineer too. Good work Dr. Somara.
Thx for this. .) I have exam next week, this is lifesaving. :) But exam is just "little" more complex but it whould start me up realy good. :) Love this channel.
Mistergamer9892 what bird? Who should get medicated if something that 99.999% of people don’t even consciously notice is actually “distracting” to you lol
What i understood : There is a probability higher than 0 that the shattered cup may come back as a whole .. What this means is that time movin'forward is an illusion made by the probabilities and our short life span (universe wise)
This is a subject so few people understand. Glad this video exists. It explains much. I took physics, but, I watched just to bone up a bit and see if maybe I missed anything. Mostly, I just forgot a lot with, well, age atrophy....sigh...
William Pereira Gomes If only there was some constant source of energy coming to the earth. I'd love to consider what source that could be, but I'd like to watch THE SUN set. (Come to think of it...it more directly disproves the theory of the origin of beings by birth and development. After all, assorted molecules from digested food becoming part of a person that grows into another adult is a blatant reduction in entropy.)
+William Pereira Gomes Little darling, I feel that ice is slowly melting Little darling, it seems like years since it's been clear Here comes the sun, here comes the sun And I say it's all right
That explains why Homer Simpson's reliance on the drinking bird to keep pressing Y on the keyboard didn't work. There has to be a small amount of energy exchange at the beak to keep the bird bobbing.
I'm a physics and youtube lover and I had to cancel the video at 4:50 because it was just too much. Did anyone actually test this content against students before release?
I once kept one of those birds going constantly for over a month! Just every 2 days or so I refilled the 'dunking' cup and it kept going 😂 In the end a build up of minerals on the beak of the bird basically prevented the beak actually coming into contact with the water :')
I hate when people say that entropy = disorder. ir gives a really wrong idea of how it works energy always tries to spread equally everywhere, it has nothing to do with order or disorder. that means entropy is closer to equilibrium than disorder.
Laff700 you could say that is the inverse. but how about crystals ? they are fruit of entropy. technically when they form they have less entropy than the space around it, but it is formed naturally when the gas or whatever try to go to a less energy state. so is it order or disorder ? the comparison doesn't make sense
+Danilo “Dantiger” Oliveira Crystallization is an exergonic process, so when crystals form, the entropy of the molecules forming the crystal decrease due to crystallization, but the entropy and thereby disorder of the overall system increases due to the released heat. Same reason why complex living organism can exists despite the 2nd law. Entropy indeed equals a state of lesser order, although 'equals a state of higher probability' fits the bill better.
I agree, entropy is a much easier concept when introduced by statistical mechanics as the logarithm of the multiplicity multiplied by boltzmann's constant
So what they mean by entropy being disorder, they mean that when something’s molecules are like, “bouncing all over the place”, like they are in a gaseous state, there is higher entropy because the molecules are in more disorder than they would be in a solid state, and more heat is being released.
Well, about that... I was let down by those songs because they got the science and reasoning wrong. The whole idea is summed up by this part: "In an isolated system, the entropy can only increase / A species set on endless growth is unsustainable". Well, first of all, in an isolated system *any* process doing non-zero work is unsustainable, endlessly growing or not. But more fundamentally, Earth is *not* an isolated system so the whole premise is wrong.
They just used the 2nd law as a way to point out the corruption of politics and the chaos they cause. "In an isolated system (corrupted country that refuses to open up), entropy (chaos and disruption) can only increase." Rather than the entropy itself.
Love your videos, but could you please able your viewers to transcript it? It would be very useful for deaf people and also those who have a hard time with your accent (even though it's beautiful! Thanks, keep that fantastic job
Homer: "Lisa, come in here please?" Lisa: **enters the room nervously** Homer: **pointing at the perpetual motion machine she made for him** "In this house we obey the laws of THERMODYNAMICS!"
Actually, a closed system is NOT isolated from the rest of the universe (stated at 2:00). Even though it CANNOT exchange mass it can exchange heat (energy). An isolated system does not exchange anything. Nice video though! P.S. I use the term "exchange" very loosely here. Cheers x
8:36- U say that the 2nd Law of Thermodynamics (i.e. entropy of the Universe always increasing) is based on high probability. Does that mean that it is possible, however unlikely, that there will be instances where the entropy of the entire universe will actually DECREASE? After all, given an eternity, anything can happen.
No it doesn't. This channel only provides examples and details of what you already know. It clarifies, not teaches you new information. What is energy? What is work? What is heat? What is a system? You should learn all the info in this video in school, this is basic stuff. Unless you are 5 years old. r u 5?
What if the universe is in a system such that any decrease in entropy of the universe will increase the entropy of the universe's surrounding, whatever that is. In addition, what if in multiverse theory, if a high entropy universe encounters a low entropy universe, the spontaneous flow of entropy from the high one into the low one causes a catastrophic event we call the Big Bang. Meanwhile, the previously high entropy universe will merge into the previously low entropy universe, such that there is now a bigger unit of universe with entropy about the average of its "parents"
It's likely just me, but for me, it feels like her lessons are concerned more about giving the 'law's and rules to remember rather than logic/common sense to describe it. Then again, I self-taught physics in high school and this is basically my first time getting lessons from someone else (in uni for physics now :) )
Scrolled through the comments looking for creationists who know nothing about Thermodynamics proclaiming that it disprove Evolution. Wasn't disappointed.
I'm surrounded by creationists in my life and I hear that nonsense all the time, sad thing is that explaining why the thermodynamic argument they use is so wrong is far too complex for them to follow through the logic. Aldous Huxley said many brilliant things but that was an exceptionally ignorant argument he stated.
+K Scott Varga framing people bcse they believe in a higher power is creating a dogmatism. its simple or the universe came to existance by a conscious force or this universe came to existence by irrational unguided force. for me the last one requirses far more believe then the first.
Their belief in a higher power isn't necessarily the issue. It is their illogical thermodynamical argument. When people go around incorrectly waving scientific terms is a problem. The irony of creationists using scientific terms to falsely support their views with discoveries made by the method they are trying to oppose is more directly dogmatic than my anecdotal statement about those in my life. However when one specifically mentions a particular belief (creationism) that has a well known argument (second law of thermodynamics) against a specific theory (evolution) it is hardly dogmatic.
the second law of thermodynamics for open systems states - everything will become dust even faster than in a closed system. - evolution goes against the thermodynamics
Well done and for once she never mentioned the idea that entropy is a measure of the unavailability of energy to do work because that is an application of entropy but not a definition of it. Measure of disorder is the correct definition.
Hello Mam, When I computed the work done in pool (billiard) the white mother ball break the 15ball. The work brought OUT is more than the work brought IN. Let’s try to compute. F = 30lbs (White Mother Ball); D = 3ft (From the white mother ball to the first ball to strike) SOLVE FOR ENERGY IN W = F X D; W = 30lbs x 3ft = 90Ft.lbs ENERGY IN SOLVE FOR ENERGY OUT First two ball extreme corner of the billiard ball 2 out of 15 ball W = F X D; W = 30lbs x 3ft = 90ft.lbs X 2ball = 180 ft. lbs The remaining ball (13pcs ball) can produce more than 90 ft.lbs The computation shows that the output work done is higher than the input work done so the theory of conservation of energy is misconception. Appreciated for your reply Thank you. Abel Urbina
The universe expands, also the universe before, we are come from out of a whitehole/blackhole is expanding. New expanding space means new place for energy and after the opened event horizon we are probably a tinier molecular universe inside a gigantic quark or something, what's mean more place for more energy.
I bet I can guess what one of the next episodes is going to be about: heat engines and heat pumps, with possible tangents to refrigerators, air conditioning, steam locomotives, and hurricanes.
The wording with "closed" and "isolated" at 01:58 isn't chosen well. Isolated systems and closed systems are both defined and they're not the same. In a nutshell: Isolated systems do not have transfer of mass or energy with the outside while closed systems can exchange energy with the outside but not mass.
Friederich Huepfenstolz this is a random low budget RUclips channel not encyclopedia Brittanica. Give them a break. Nitpicking verbiage intricacies is irrelevant considering most people watching this are novices on the topic.
Know what would help a lot with remembering all these sci-ency words? An understanding of etymology of Latin and Greek words of course! You could drop some of that knowledge in the Crash Course Lin-guist-ics course you should do! Pretty please.
Forgive me for sounding nit-picky but, Perhaps the 2nd Law would have been better explained with the description of Exergy and how it relates to Entropy: The 2nd Law describes the quality of the energy being exchanged; that is energy must be conserved, but work may be destroyed in a non-perfect system. In other words, its the Law of Conservation of Exergy/ Generated Entropy.
OSILVEROBULLETO the way she explained it is exactly how it would be explained in a lower level physics class and is the basis of the law
5 лет назад
The first law of thermoodynamics state that heat energy cannot be created or destroyed. So then why is it taught that when matter meets anti-matter it is destroyed. This contradicts the first law of thermodynamics. Plz explain in depth. thanks
Wait- around 2:15 she says that the First Law only describes Heat and Work, because if a system is closed, then those are the only two things, and they're equal to each other. Therefore, she says, the First Law is just restating the Conservation of Energy. But in that case, wouldn't deltaU just be 0, making the term unnecessary? I understand the Law, but I'm not sure she explained that correctly. Or am I misunderstanding?

Came here so I could fully understand The 2nd Law songs by Muse
I listened to Unsustainable whilst studying thermodynamics. Singing it in your head during a test is quite effective.

Hello Mam,
When I computed the work done in pool (billiard) the white mother ball break the 15ball. The work brought OUT is more than the work brought IN. Let’s try to compute.
F = 30lbs (White Mother Ball); D = 3ft (From the white mother ball to the first ball to strike)
SOLVE FOR ENERGY IN
W = F X D; W = 30lbs x 3ft = 90Ft.lbs ENERGY IN
SOLVE FOR ENERGY OUT
First two ball extreme corner of the billiard ball 2 out of 15 ball
W = F X D; W = 30lbs x 3ft = 90ft.lbs X 2ball = 180 ft. lbs
The remaining ball (13pcs ball) can produce more than 90 ft.lbs
The computation shows that the output work done is higher than the input work done
so the theory of conservation of energy is misconception.
Appreciated for your reply

Know what would help a lot with remembering all these sci-ency words? An understanding of etymology of Latin and Greek words of course! You could drop some of that knowledge in the Crash Course Lin-guist-ics course you should do! Pretty please.
such an amazing channel
Love u Doctor
awesome editing !
Forgive me for sounding nit-picky but,
Perhaps the 2nd Law would have been better explained with the description of Exergy and how it relates to Entropy:
The 2nd Law describes the quality of the energy being exchanged; that is energy must be conserved, but work may be destroyed in a non-perfect system.
In other words, its the Law of Conservation of Exergy/ Generated Entropy.
OSILVEROBULLETO the way she explained it is exactly how it would be explained in a lower level physics class and is the basis of the law
The first law of thermoodynamics state that heat energy cannot be created or destroyed. So then why is it taught that when matter meets anti-matter it is destroyed. This contradicts the first law of thermodynamics. Plz explain in depth. thanks
great vid
Wait- around 2:15 she says that the First Law only describes Heat and Work, because if a system is closed, then those are the only two things, and they're equal to each other. Therefore, she says, the First Law is just restating the Conservation of Energy. But in that case, wouldn't deltaU just be 0, making the term unnecessary?
I understand the Law, but I'm not sure she explained that correctly. Or am I misunderstanding?
i love this teacher
have you done a video on the zeroth law?
Now come the best part of physic!!
This is excellent. I enjoy the speaking pace actually. I can't stand slow talkers.
