Second Law of Thermodynamics 

The 2nd Law of Thermo, in layman's terms, is: "Things, when left to themselves, tend to proceed from a state of greater order to a state of lesser order." Your so-called closed system only become more ordered because you provided creative input from outside said system, ... ie, you didn't leave it alone.

I watched several videos about entropy (after reading about it in a textbook) and your video with its examples really clarified the concept for me in a more useful way. Thanks.

4 years after i needed to somehow learn this stuff, i still come back and LOVE Bozeman's series. Thank you again Mr. Andersen!! And the examples and explanation are for everyone. Genius stuff. Helped get me through college, and eternally grateful tbqf

I can't believe you don't have more views; you're videos are the best for conceptualizing concepts which are simply stated monotonously in textbooks!

wow! This video awakened and enlightened me for my exam tomorrow. Thanks!

This video explained this difficult concept very well. Thank you!

Thank you for making videos. Keep up the good work.

Good explanation, really clear video, thanks man.

This is a great video! Thank you!

Great video. I watched a few on this topic but they couldn't explain it as well and as simply as this one did. You could usually tell if people have a good understanding of something by how well they could explain it to others. 😊👍

Thank you Professor Andersen!!!

thank you for this video! It was helpful for homework.

Excellent explanation.

Very clear. Thank you.

Every time I search a video and see your face, I'm like, thank god, I'll actually be able to understand this time. You're even better than ChatGBT as of writing this! I loved the universe picture at the end to nail home the point. So clear like that!

So... this says that the order of life is so improbable that its impossible..... therefore pointing toward a creator that must have arranged things into order.... got it

So for earth to form doesn’t that violate entropy? As were told it was just random gases that started to collect. And form. That seem to violate entropy. As it should of gradually increased entropy not decreased.

Prof. Paul, may I request to please correct me if I am wrong. Wikipedia meaning of explosion: An explosion is a rapid increase in volume and release of energy in an extreme manner The applications of explosion in the system the principle of Thermodynamics fail. The Internal Energy is multiple times lower than the work done by the system or The WORK OUTPUT is multiple times higher than the WORK INPUT I. A 15 ball billiard pool to be strike by white mother ball. F = 30lbs (White Mother Ball); D = 3ft (Distance from the white mother ball to the first ball to strike); W = Work, F = force; D = Distance The mother ball to strike the 15 ball is the work input The first collision is explosion followed by increase in force and travelled distance by individual ball followed again a series of collisions. The mother ball transferred the force to the group of 15ball. The momentum is conserved to the group of 15 while the explosion increases to 15 individual ball. The kinetic energy was absorbed by the group of 15ball. The explosion increases rapidly multiplied to 15ball individual. SOLVE FOR WORK INPUT W = F X D; W = 30lbs x 3ft = 90Ft.lbs SOLVE FOR WORK OUTPUT W = F X D; W = 30lbs x 3ft = 90ft.lbs X 15ball = 1,350 ft-lbs. II. For more heat energy the ball to replace with steel ball and steel side board. After strike are explosions of 15 balls. The explosion increases the group energy into individual 15. The work output higher than work input followed by series of collisions that produces more heat more work output, more sound energy more work output, more travelling distance more work output. III. To get even more energy output: Put additional two group of 6balls in triangular shape to be placed somewhere at the back of 15balls at least 4inches apart from the sidewall and back wall. A total of 15balls + 6balls + 6balls = 21balls. The explosion creates collisions after collisions increasing the energy output. The Internal Energy in I, II, III are the same however, after explosion the work done increasing 15 times the Internal Energy. That principle can use to make free energy machine. Thank you.

Excellent video!

it was helpful. thank you

This makes me curious as to how the world is at such a harmonious state if things only become more chaotic over time unless there is some kind of intelligent intervention?

Thank you so much 🌹

The secound law of thermodynamics is my favorite law of the universe, even though it makes life harder. Whenever order is established an equal or greater amount of chaos is released. If more people knew about the secound law thermodynamics then they would understand why complete world peace is impossible, unless we obtain an extreme amount of energy.

it was helpful your always are.

Thank you for posting this. A question. Do you mean a closed system or an isolated system?

Thanks. That made sense.

You are blessed. ...Great.

Very clear ...............

really helpful

Thank you so much. I want some explaination about exergy if you can please.

excellent .Thanks

A is forward because I can see your Hand's Shadow

You are one of the best teachers i ever had. Anyone here saw T E N E T It's related to entropy😁

Cool video, but I would have loved more explanation around closed systems

Bozy gr8 explanation

This man is a real TEACHER😌

Yes, it was helpful

Decreasing entropy always requires a controlled application of energy.

So how do you get a human eyeball from the irreversible Entropy that the universe is?

Bozeman can you explain the second law of use the example of a car and stove

The video is done well. I just had one problem/question: Why do you say that the blocks getting back up from falling down is statistically improbable? I would say it's impossible for the blocks to get back up unless you pick them up and stack them there.

thank you!

thank you

Do people highly educated in thermodynamic physics know of a higher consideration of nature that overrides accepting that diodes can rectify Johnson - Nyquest thermal noise power and, given the orderliness of consistent orientation in parallel, aggregate a DC residue from each diode into electrical power at any scale coproduced with refrigeration of equivalent thermal energy absorbtion?

Don‘t you mean isolated system as opposed to a closed one?

What is an aneroid barometer workdone in joules per cell cylinder volume changing by virtue of which it can turned the needle ? Please tell Please Please

In the examples, is gravity reason for entropy? Does gravity spread matter more diluted and evenly?

Plzzz make a video on first and third law too. Plzzzzzzzzz

Nice

Will it be possible to explain osmosis using concept of entropy

Thank you for your video! I was having a debate with a religious person whose argument is "2nd law of thermodynamics is a proof of god." So I wanted to see what it means.

So to make something more ordered you actually cause more disorder to achieve it.

great

Is the universe as a whole a closed system or open?

I like his bored "seen it all" expression

gravity plays a part. reverse can never happen due to gravity on the milk in glass.

Someone tell me about entropy in higher dimension??

GOOD

why is disorder equates to less heat?

can you explain why 100% of the heat cannot be converted to work?

'In the direction of time', 'arrow of time', Do You really believe in this, Who is actually shaping your time.

Hmmm... I understood the concept... now lets talk about solving a problem

So it's called irreversible only because of a statistical improbability? I'm asking because the 2nd law is considered a fundamental law. You see what I'm getting at :)

Entropy will finally bring peace and harmony as differences are reduced.

That last example is wrong; a computer over time will degrade aka fans start to loose its functionality etc etc therefore making a PC and a computer or laptop follow a closed loop system; there are ways of slowing down the failures but overall its headed towards a disordered system

Does the "theory" of Evolution comply with the laws of Thermodynamics?

Please be my professor! 💜

whats an example of a closed system? and I did not understand the computer/video "order" example at all, I feel like i will never understand this concept, makes no sense to me whatsoever and the more i try to understand it the worse it gets

The concept of "disorder" when trying to explain entropy is misleading, but, fortunately, is turning obsolete. What are the units of entropy? How about attacking the concept as Boltzmann did? Some statistics (probability) perhaps? Better to check ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kfffy12uQ7g.html

After watch this video. I understood my weakness

how do u define randomness scientifically

What is the 19 Letter in the English Alphabet?

chaos and disorder are subjective.

So basically no on can die...ressurect...and elevate into the sky post-death? 🤔 #Bummer

Wahoo

Evolution is an irreversible process according to the 2nd law of Thermodynamics.

I think the videos you use aren't the best examples. You could argue that milk doesn't float up due to gravity, and blocks don't spontaneously assemble (and move themselves upwards) for the same reason. I think a drop of food coloring in water would be a more instructive example as collecting together into a single drop doesn't violate gravity or any obvious physical laws, only the 2nd law.

Who thumbed it down?

That law is clearly broken. There's one thing you missed when you said the "Universe". What you missed is We are in the Universe, as are many more life forms. As you stated, you made that video and someone else made the computer. No matter how you measure it. The Spirit of Creation is at work. Proof is, Stars among other forms of life arn't losing energy to entropy. They sow the seeds of life.

nope

No evolution then no life from non life

You wanna know an idea that violates the second law of thermodynamics? Outer Space

not at all!!

Spoilers!! Watch this video after you watch Tenet

entropy does not exist becouse disorder does not exist .All the things happen becouse of order.

Just click to say i hate entropy

Entropy is not going to increase over time, because our conscious understanding escapes it with order higher than its surroundings. Thinking would be an evil process if that were not so. Some people think so cosmically, that their thoughts organize their environment and relate to time in ... entropy! help!

never be a teacher

Very bad video - entropy is NOT a measure of disorder or chaos. Very disappointing.
