Gibbs Free Energy 

Thank you for the hip music in the intro. I got to have a short dance before I got back to studying.

Honestly, this is the first time I've understood what's going on when someone says "Gibbs free energy." An absolute legend

Dear Paul + your esteemed audience, First of all, many sincere thanks for your collective efforts! You attempt to explain Gibbs Free Energy. You begin by using three spontaneous reactions to explain how a change in enthalpy, entropy and temperature can affect the free energy of a system. You then apply this concept to cellular respiration and photosynthesis. ...sounds terrific, but even big scientific research workers' brains had and still have to stumble herewith... In fact, Prof. Gibbs had learned what ENTROPY exactly IS while attending chemical thermodynamics lectures by Prof. Horstmann in Heidelberg, whereas Prof. Horstmann was one of the very students of Prof. Clausius. Prof. Gibbs was duly heading for the proper embodiment of the Clausius-Horstmann ideas (in fact, Carnot-Clausius-Horstmann ideas, to be correct!), but he had not enough time for accomplishing this, to our sincere regret... Dr. George Augustus Linhart was one of the very rare true followers to Prof. Gibbs, but he had very bad luck... ...It's a truly long and interesting story - hence, some kind of a concise clarification ought to be urgently necessary! So, captain, AHOY! A. There is ONLY ONE BASIC, fundamental Energy Conservation and Transformation Law. It is definitely unique and conceptually indivisible delivering two logically joint concepts - these are Energy Conservation - and Energy Transformation. Still, a more-then-100-years-old conceptual failure has brought us to two separate thermodynamic laws - but this has nothing in common with the actual physics. To come back, they have coined two more fake thermodynamic laws, employed the Probability Theory + Mathematical Statistics, and this has helped formulate the Quantum Mechanics, which is thus a basically metaphysical conceptual construction - and, hence, ought to be only restrictedly fruitful. B. By dividing the basically indivisible law, you are touching Combinatorics, you are touching Probability Theory, you are even stepping back to Thermodynamics for a while, but... You are NOT answering the poser: WHAT IS ENTROPY, sorry! 1. In the formula S = kB * ln(Ω) you do imply, Ω means not a "Huge Number of Microstates", not "Probability", which numerically ranges between [0,1], not even "Wavefunction", which ought to be a purely metaphysical notion, as it is... In effect, Ω ought to be a simplistic algebraic function of Lord Kelvin's Absolute Temperature. This result has been published 100 years ago in JACS by Dr. George Augustus Linhart. 2. WHAT-ENTROPY-IS-poser has been answered not by Clausius, not by Boltzmann, etc., but by Goethe, who has introduced Mephistopheles, the philosophical embodiment of ENTROPY. 3. Newton did basically know WHAT ENTROPY IS - A Counteraction. 4. That Counteractions do not grow to infinity with the growing Actions, but MUST reach their MAXIMUM values, is the result by Nicky Carnot, which has been formalized by Clausius... 5. In effect, J. W. Gibbs Free Energy formula: (ΔG = U + pV - TS, .i.e., ΔG = H - TS, where U is the internal energy (SI unit: joule), p is pressure (SI unit: pascal), V is volume (SI unit: m3 = m*m*m), T is the temperature (SI unit: kelvin), S is the entropy (SI unit: joule per kelvin), H is the enthalpy (SI unit: joule)) renders implicit the interplay among ALL the relevant Actions (the Enthalpic term) and ALL the pertinent Counteractions (the Entropic term). 6. The standard approach you are reporting about is OK for the implicit Enthalpy-Entropy picture, employing it, e.g., for studying reaction mechanism details is likewise eating soup with a fork. The above is about "Entropy" in Physics, Chemistry, Biology, etc., etc., etc. ... Entropy in other fields: Be aware of a powerful trend to build up misnomers in many other fields, for Entropy is the proper term solely for the "Energy Transformation", whatever nature/origin this energy might be of. The Arrow of Time: This is not due solely to Entropy, but owing to Eternal Entropy-Enthalpy Compensation. This is why, the Heat Death morons are proclaiming over and over again ought to be just a useless legacy.

I cant believe this is 11 years old, I wish I had saw Mr Andersons videos a long time ago. He is awesome.

the world would be so much smarter if we got to have teachers like you!

I know he probably doesn't need it at all BUT IS THERE ANY WAY TO DONATE SOME MONEY TO THIS GUY?! I really really appreciate his stuff and I want to support his work. Can't even imagine how studying some of these things would be without him.

I could never understand Gibbs Free Energy in my past 16 years of education, but after spending 13 minutes on this video, I know very well understand it. Thank you Paul, you are a great teacher.

Real teacher are like u who understands well as well how to teach it well⭐

As a Physics teacher I must say that your method of teaching entropy is really thoughtfully prepared and excellently presented. It makes it accessible to students.

Simple and clear explanation in 13 minutes. You deserve to get a Nobel Prize

I especially like the part of this video that you explained enthalpy and free energy as total energy and available energy to work, respectively. It’s easier for me to understand those things. Thank you.

A great teacher indeed! This issue is a nightmare for every higher Chemistry student. Many thanks Sir for your wonderful examples and splendid explanations!

I love your videos.....when you can explain something using everyday examples, rather than scientific jargon straight up, it makes the scientific jargon so much easier to comprehend. I wish all teachers used examples like yourself. Thank you again for a awesome video :)

Thank you so much for your videos. Your videos combined with Tyler De Witt's videos are making my correspondence biochemistry possible to understand.

I'm about ten steps closer to fully understanding this concept after watching such a short clip. I can't thank you enough. work like yours makes intellectual discourses accessible to the masses! This is amazing. You're amazing. I love you.

Literally, in my senior year for biochem and I have never been able to make sense of this. Thank you.

I'm a supplemental instructor for a biology 1 course and I'm going to show this to my students today! Best explanation I've ever heard for free energy.

I love him - He truly understands how to teach. I am a teacher and he is few and far between. Excellent job.

Who are those people dares to downvote this! What they think of themselves? 'Dash'hole? This is a great video ! Thank you so much . Infinite upvote !

FINALLY A TEACHER THAT KNOWS MORE THAN JUST DEFINITIONS. THANK YOU!

Thanks a lot man. Now my mind's entropy decreases. You have cleared such complicated terms in an awesome way

Wow, man ,thank you ,may good things happen to you.this video deserves hundreds of ads and plugins.i thank you bro , words are not enough.

Thanks a ton Mr. Anderson! You're awesome!

You are awesome! Thanks for all your videos, they help me so much in understanding how things are tied together and how they work :) Greetings from Sweden

Thank you so much! I've watched many other videos on the topic but yours was the most helpful one. I finally got it!

Sometimes I think I learn more from RU-vid then my teachers.

I am a freshman taking biology and frankly I'm a little lost sometimes, my teacher gave us a project and part was to explain the terms ATP, Endergonic, Exergonic, and free energy. The other part is explaining what these mean in reference to cellular respiration and photosynthesis. I have looked through lots of the internet, databases, and textbooks and this was the one thing I found that I understood and it answered all my questions so thank you.

thanx for the music in begining to energetic me to understand what is free energy...i always obey ur all concepts...(STOP MEMORISING START UNDERSTANDING)

you literally saved my life for bio and i'm getting a 97 because of you. thank you so much!

Wow, I understand it so much better by now! Thank you so much for this video!

Your explanation has a marvelous attraction towards online study, appreciate you for that.

Thank you so much Paul! I now have this concept in the bag!

You are the reason why I made it into university, bless your soul

Your vid is awesome man, I hope you can keep doing this kind of really useful stuff.

I am a sophomore in AP Biology. I can't tell you how much this is helping me right now!

Great work ! Love the addition of natural world examples to Gibbs.

APPRECIATION POST: HONESTLY THIS GUY CLEARED ALL THE DOUBT, CONFUSION AND BOREDOM I HAVE ABOUT GIBBS FREE ENERGY.

I have a test tomorrow and you just make me so much more confident!! Thank you so much!

The best explanation of Gibbs Free Energy I've ever seen, hands down 😉

Thank you! I've been struggling on this topic forever now. and it finally makes more sense :D

thank you soooo much for this! this was the one thing i really needed brushing up on before the ap bio exam, now i think i've got it! :)

The best explanation I've ever come across

Extremely well done! First time I have really understood this!

Extremely grateful to you. Greatly explained. Huge thanks 😊

I thought I would never understand Gibbs's free energy., now it's clear., thanks bro., u r awesome

Short sweet and well done! Thank you.

This was my first explanation ever.. im glad it was you thanks!

Thank you VERY much Mr. Andersen. it helped me a lot...

You've explained very clearly, thanks a lot!

You suceeded! Best explaination of gibbs " free" energy i've ever seen!!!

This explanation is very interesting and fun for me and it’s very helpful because it’s a little difficult to find some applications in nature except examples of some mechanical systems although I learned Gibbs free energy in thermodynamics in physics. Thank you for uploading this video.

Thanks Sir....so well-illustrated.

Thank you SO MUCH. This is amazing and clear!

Made so simple and clear, thanks so much

Great explanation! Thank you so much

This is super helpful! I am a student from Taiwan. I am blessed to watch this awesome video.

Thank you so so much for this vid; I'm way less confused now! Also, I really liked the colorful visuals :D

You sir know how to teach. I wish more so-called teachers would take note.

Thank you really really thank you..For finally making this thing a bit sense

Thank you so much for your videos man! You are helping me with my chemistry exam.

thank you Mr Andersen ! you really make it easy !! ♥♥

Thanks a lot, you explain the concept very clear and easy to understand.

Extremely helpful video! Thank you!!

Thanks a lot... Gibbs free energy concept was always such a confusion for me.. u made it very clear & easy to understand..

Thank you for the great explanation! I was getting so confused in my chem class!

Loved your explanation

Love this Video! It makes the jibberish I was reading totally understandable! Thank you, thank you, thank you!

It's soooo easy to understand..... Thank you for cracking that big problematic topic into simpler one.

thanks a lot Mr. Anderson, I swear you teach this way better than my teacher.

Great video as always

Thanks for your videos! Best Chem videos online for MCAT prep!

Thank you so much! You really helped me out...you have earned a subscriber my friend!

im thankful..for your great lecture ..sir..im struggle from few days about the basics of gibbs free energy which i missed in gardute level..thank you .so much .sir

your lectures are always helpful

Woooow the lesson is amazing... learning this is simply a spontaneous process

Don't get misguided! Total energy remains constant, as explained in the "ball rolling down" example, it's true that the gravitational potential energy decreases as the ball moves down and also not to forget the ball speeds up the moment it comes under motion and hence the kinetic energy increases as it rolls down. Total energy is the sum of kinetic and potential energy. To conclude as the potential energy decreases, the kinetic energy increases and thus the total energy is conserved.

Video was extremely helpful and easy to understand. Thank you!

AP Chem student here. One thing that is commonly misconstrued is that breaking bonds releases energy, as you implied around 7:50. Energy is absorbed to break the bonds of the glucose, and then energy is released again when the bonds of water and carbon dioxide are made. The energy released when making bonds of water and carbon dioxide is larger than the energy absorbed when breaking bonds of glucose - that is why energy is released, not because breaking the glucose bonds releases energy. Am I right, or have I confused something?

good job linking concepts

Thanks！This video helps a lot！

Thanks for posting. Good graphics of the concept!

best explanation i've ever seen

Really good explanation, thank you!

For the first time in my life i hv understood what Gibbs free energy really is without a doubt!. Damn,Thank you!,,

Thanks a lot for the nice video, this is a masterpiece :)

i have only 5 words to say about this video : awesome ! awsome ! awesome ! awesome ! thnaks !!!!!!

This was so helpful! Thank you!!!

You are really a perfect teacher. Thanks a ton to God to sent you on Earth

This was really helpful, thank you!

This was an awsome video I appreciate all the effort :) but I have one nitpick, I think that it's dangerous to say energy is stored in bonds because you can cause confusion by saying that the energy is stored and that the breaking of those bond releases energy when in fact the formation of bonds is what gives off the energy and the breaking of bonds is what requires energy. the energy given off or required is strictly the energy differences between the reactants and products ;)

Wonderful explanation of natural phenomenons ,,,, nice video

You are a brilliant teacher, thank you :) :) :)

Thnq soo much man Tq u cleared my concept and helped me a lot Plzzz post more videos I love the way u teach same as my sir like giving examples :)

Thank you so much!!! Everything just clicked.

I just want to say that GOD LITERALLY BLESS YOU. I had a rough time understanding this conceopt

Thanks, I was stumped on this one question for my coursework

WOW! great teaching style! very helpful

Thank you very much, best video found about free energy

Alright, imagine throwing a party. Gibbs free energy is like a party budget. If the budget is negative, it means your party is happening spontaneously - people are excited and things are happening on their own. If it's positive, you might need to put in some effort (add energy) to get the party started. If it's zero, the party is in a balanced state. So, in chemistry, a negative Gibbs free energy means a reaction can occur on its own, while a positive value may need a push, like adding heat or other energy. It's all about the energy dance at the molecular party!

You nailed it sir, thank you.
