If you would like a more comprehensive explanation of these laws, go to my classical physics playlist! Clips 28-31 cover the four laws, one law per video, and they are much more in depth than what is mentioned here!

The only thermodynamics I know have to do with lawyers
Comment from : Skeletøn

So easy to understand in theory yet so difficult to solve mathematical questions on them 😭

Now I have understood Gibbs Free Energy from you my Professor ❤
Comment from : Immaculate Mphepo

Sorry, a late comment I am a big fan of youbrbrThis is perhaps the best under 10 minute lecture of Intro to Thermodynamics I have seenbrbrVery few people can explain a very difficult subject as clearly as this!brbrI would give this a big 10 thumbs up if I could
Comment from : Ken Wada

Isn't the second law actually always increasing OR staying the same Like if I have a water bottle in my room it will reach room temperature and unless the temperature of the room changes, the water temp stays the same
Comment from : Aistle

considering your example of hot coffee cup, can't the same principle be applied to cold objects?brcold objects too have heat energy, so, even for those objects, entropy will be higher if they disperse away that little amount of heat energy they have just like that hot coffee cup does meaning all objects should disperse away heat until they reach absolute zero temp but that doesn't happen, can someone explain why ?
Comment from : john rhodes

Why does stretching a rubber band decrease its entropy? I get that the molecules themselves are more aligned, but what effect does that have on energy spread ie entropy?
Comment from : Bilbo Baggins

So basically a self starting motor that requires no energy input is possible Funny how industry uses this law as a way to stomp out any and all competition by handing out a university grant to have their professors regurgitate their nonsense 😆

Degrees kelvin has to do with how orderly something is?
Comment from : Ross Friedman

The law of entropy only applies to a closed system As far as we know there is no such thing as a closed system And even if there are closed systems the systems people are applying it to are not closed Let’s try to be more accurate with how we are applying this “law”
Comment from : FUN SPLASH!

2nd law only applies to closed system No such thing as a closed system
Comment from : Ray Truck

Professor Dave, I always enjoy watch your YouTube videos and admire you for working so hard to educate others Big Thanks!
Comment from : Al

Is anyone able to explain what is untrue about conservation of energy at the quantum level that he said? I know quantum mechanics is very weird but I've yet to hear that energy isn't conserved and was wondering if anyone could explain Thank you
Comment from : Tyler Hurlimann

Gibbs free energy? More like "Great free lectures for me!"
Comment from : samter

I thought there were four laws of thermodynamics, did I miss you mentioning one?
Comment from : Accept Jesus as your savior

Untruebad defines, entropy is actually the idea that there is an energy black hole, energy moves to thermal energy and it cannot retrieved
Comment from : Robert Butwell

The 2nd law is actually the actuality of of a one way valve for certain kinds of enrrgy
Comment from : Robert Butwell

That doesn't explain why an ice cube melts in water Thevice cube melts for two reasons 1 Kininetic energy can be shared continuously 2 When a fast molecule hits a slow molecule, thevfast transfers energy to the slow
Comment from : Robert Butwell

I will literally starting watching your videos every sunday religiously
Comment from : Mr finge

Didn't want to search for "Thermodynamics chemistry class 11" and I don't take thermodynamics classes, but I watched this whole video anyways
Comment from : Belinda Loney

thanks for being so good in explaining ,i found best channel for my doubts just a few day backI really appreciate your approach ,please keep clearing the concepts and making it easy for us to understand Thanks sir

Comment from : Ayham Riyadh

Thanks a lot At least I can grasp a little with with overtly science and mathematics negative cognitive system
Comment from : avbhinaya

When we say positive entropy means more disorder, how does that relate to the idea that two objects with a temperature difference, and in contact, reach the same temperature? How is reaching the same temperature "more disorder"?
Comment from : Robert Destefano

Studying for biochem exam! Thank you so much this is way better than the long ass lecture videos that I get from my lecturer😭😭😭💖💖💖
Comment from : Ruth Wang

I can't believe you literally made me understand this concept in 8minYou're so amazing
Comment from : Ruth Wang

Signing off Prof!! You've been an integral part of my Physical and Organic Chemistry for the last two years in my PCM(Indian version of STEM)brbrIts been a good time and a wholesome experience learning new things quite efficiently from you but somethings have to end
Comment from : Asmit Sharma

This really helped me better understand conceptually how Gibbs free energy relates to spinoidal decomposition and thermodynamics in general, thank you
Comment from : Dustin Dickens

Thanks!
Comment from : Dustin Dickens

thank you chemistry Jesus
Comment from : Lee Vidal

Actually micellisation is generally entropically driven not enthalpically driven Whilst both the enthaplic and entropic contributions to the Gibbs Free Energy are favourable the entropic contribution is generally 3 times greater for detergent like molecules For very short chain surfactants the enthalpic contribution is more significant Whilst the micellar solution might look like a more ordered system it is not actually the case This is because the hydrocarbon chains have more mobility within a micelle and the water that surrounds the hydrophobic chains in solution is highly ordered and this is eliminated when the micelles form, these effects are more significant than the 'ordering' of monomers in a micellebr
Comment from : Vince Craig

Disorder is not a good word for this process Energy is dispersed Read Lambert's work on entropy
Comment from : Charles King

There must be a more favorable word than “favorable” to serve the purpose
Comment from : Phil G

thank u , professor Dave brur way of explaining is amicable ✨brlots of love from india 🇮🇳
Comment from : Uק rΐsΐŇg

omg thank you so much for your videos Dave! (greetings from Greece)
Comment from : RandomAF

Nice mathBut what are we creating or not creating? Science please and its relation to mankind?
Comment from : T ruth

6:18 yikes that's in the trypophobia ballpark
Comment from : Phil G

Very Well explainedbrthank u so much
Comment from : Utkarsh Tuteja

Oh my god this explains soap so well!
Comment from : rentaspoon

3:19- now I understand why as volume of gas increases, so does entropy!
Comment from : Sabina Dorothea

Thank you Jesus, for blessing us with a comprehensive video on the laws of thermodynamics, entropy, and gibbs free energy Thank you also, for dying for our sins

Anyone focused on the computer code?👀
Comment from : DolfinW

Thanks
Comment from : ʟouvʀe•ᴋiosx

Thanks for the content Have you seen anything about these mathematics applied to whole societies I recently found a direct link between entropy and trepidation pie root "Trep" finally after seeing a great deal of synchronicity with these ideas and theories at the heart of cognitive science as well as metaphysics going way back, old sciences when they were still very connected to spirituality brMy short deep dive into linguistics has shown some intriguing parallels not to mention light being described as energy and information If laws can be applied to energy they should also be applied to understanding flow of information/knowledge regarding society as a whole and may perhaps scale to also include the entire *masses of civilization back throughout time It's clear to see these pillars were there at the inception of cognitive science and even further into the great myths They can easily be applied to human chemistry but does it apply to the masses and civilizations? I'm not a math wiz though and not enough time to become one If you have heard of any philosophy or greats speak in regards please let me know
Comment from : hobo nickel

Your videos have given me an early headstart into what my chemistry course will be mainly about Thanks for the detailed explanation! 😀
Comment from : Bradley Freeman

So does soap have low entropy
Comment from : Chay Millan

But you said the laws may not apply in quantum mechanics, which I think you were wrong
Comment from : Hozan Ziyad

Great

6:00 how entropy favorably decreases * an exception
Comment from : Edmond MacLerie

is dude reading off a script??🤣🤣
Comment from : GamerzGuff7

I didn’t understand much
Comment from : JaxKiller

If solids are more organized than liquids, why in the "heat death" of the universe, which if I understand correctly, means entropy at its maximum, everything will be frozen solid?
Comment from : Erick Rocha

Why are there so many entropy videos that claim it’s a mistake to say entropy is a measure of disorder?
Comment from : Tim Gray

Good video teach the children well
Comment from : Mark Danielson

Hii professor Dave!! I'm from India🇮🇳, watching your video to understand my concept For me, you look like a ranveer Kapoor (Indian actor)😃
Comment from : Riya soni

youtube has helped many university students realise that university is a scam

Comment from : Mulat Adane

Whoever watching this before an exam, GOOD LUCK, MAY THE GOD BE WITH US!!!!
Comment from : Daniel

I know I am late but I have a questionCO2 and H2O at normal condition would have more energy spread out(more entropy) compared to glucose but when they combine in a presence of sunlight, they form glucose in which energy is concentrated(less entropy)But the overall entropy of the universe is only going to increaseSo, more energy have to spread out in order to compensate for the local entropy increaseMy question is "where does the energy spread out?"
Comment from : Myat Min Soe

I was pretty confused at 6:24 as polar heads of soap molecules maximize ion-dipole interactions with water molecules but not dipole-dipole interactions I never knew those polar heads are ionic Thanks Professor Dave!!
Comment from : Phuong Pham

Im literally going to fail my entropy report tomorrow 😢
Comment from : Jaidie Mae Dosdos

Im confident I can hold my own against some of the greatest minds today This my 4th entropy video n I'm more confused than when I started
Comment from : Antwoine Lesley

cool
Comment from : cerise clevor

I only watched this because of the song called thermodynamix
Comment from : rico goins

I know you said that the universe is in entrophy but with enough time would life not come from the completely disordered chaos again? Another big bang so to speak starting the cycle all over again?
Comment from : Danielle Sebire

I literally don’t understand how good you are at teaching Like omg
Comment from : Evelyn Tromp

now i know how soap works!
Comment from : Swagatika Dash

Imagine if… We were smart and populated other planets… only a dumbass wouldn’t listen to the planet for signs
Comment from : Frank Rizzo

According to cosmic evolution theory, galaxies evolved and formed by gravity So the evolution process proves that energy can be transferred from low to high energy

Nice sir 👍
Comment from : Rajput artist

Understandable class Thanks Sir :)
Comment from : Fayaz

very helpful video, thanks a lot!
Comment from : Fabri Ortiz Morales

I didn't understand that so I'm still going to try and create perpetual motion
Comment from : Matthew Turner

So what I took away from this philosophically is that the world will always be increasing in chaos but in your personal life stored energy can leave conditions favorable enough that you spontaneously find order that can wash off some of the chaos if you know howmaybe I missed the mark but that's the way my ears translated it
