Second Law of Thermodynamics - Heat Energy, Entropy & Spontaneous Processes
Вставка
- Опубліковано 3 гру 2017
- This physics video tutorial provides a basic introduction into the second law of thermodynamics. It explains why heat flows from a hot object to a cold object. The second law of thermodynamics states that the change in entropy of a natural process is always a positive. For an ideal reversible process, the entropy change is equal to or greater than zero.

man went crazy with the analogies
and good thing he did because is had no clue what my professor was talking about
Try this video ... ua-cam.com/video/Y-UFMnuZnn8/v-deo.html
So that a guy like me can understand

Jesus bless you
they should give this guy a Nobel Prize for helping students better than their actual teachers
wat u meaeanin
Who is actual teacher? Isn't the one who teaches or who takes money from from students??
Jesus bless you

Broo organic chemistry tutor is a frickin genius. I didn't expect him to actually cover topics in my 2nd year engineering course but here it is. I've been watching him since highschool.
2nd year engineering?😂😂 all of this is taught in 11th grade in india
@@arex6240 indian system pressurizes kids more than they can handle , this is not a flex
@@arex6240 classic Indian not being able to control bragging about how hard school is for 5 minutes
i want to thank u for saving me from our poor education system that is fixated on memorizing stuff instead of actually understanding them jdkajskdjs thank u
Haha same I'm studying the CBSE curriculum 😓
Force feed and regurgitate :(
Are you from India?
Specifically in the online learning days. You are being fed the science not taught

oh, this why my life is falling apart.
Hahahaha I feel you!!!!
Dead😂💀
@@lonicocopuffs I'll call the ambulance
@@hypegoodsincorporated5784 😂😂😂😂😂
It's just the way of the universe my good sir. Nothing to do with you
Oh man, his analogies are the bestt🥲🥲🥲🥲
Thanks so much! You explain so clearly. The analogies help me understand the topic better :)
The entropy of our education system is increasing but you are trying to control that! Thank you Professor!!
Respect from India!!❤️ Whole world is one family!!
We are one ❤
Such a clear explanation, thank you!
I wish my professor explained things this clear!! Thank you.
Great examples that you for making this concept clear.
taking a more philisophical approach to this concept here, but it seems like this can be applied to our everyday lives as well! As you notice things start to fall apart around you, you must put in the ENERGY and WORK in order to reverse these processes...very interesting
Very well explained. Thank you🙏
You are Gifted. Big respec from Verlin
You're so good
that's what I call teaching.
Theee explanation is 🔛🔝
Thankyouuuu it helped me
great analogy!
You are always the best
😂😂😂😂I ran away from physics because I never understood anything, but I still got it in power engineering and thanks to you I never understood so well in 2 years of prep. even if I don't have a good grade I would still have understood. THANKS😊
Thank you very much sir
You are excellent.
thanks a ton sir!
I owe you everything fr
thank you!
Thanks a lot I really liked your simple examples
hi reemhraez, have you become a flat earther yet?
I can't explain how much you have helped me and my classmates...my professor should send you his salary
Thank you 👍😊
thank you so much
Sir you are the best
You rock!
he just summarise my 2 week worth of lesson in 4 minutes
thank you
you rock
Awit sa handout d2, thx gg
Can heat flow from dry ice to ice because of the temperature difference between the cold and colder body?
Can we run the Sterling engine by using ice as the source of heat and dry ice as the sink?
Heat is the difference between temperature, the change in internal energy isn't heat. LOT makes it perfectly clear Energy, Heat and Temperature although closely related are not the exact same thing. I'm hoping you learned this already in the last 5 years but your never know?
>“Heat is defined as the form of energy that is transferred across a boundary by virtue of a temperature difference or temperature gradient. Implied in this definition is the very important fact that a body never contains heat, but that heat is identified as heat only as it crosses the boundary. Thus, heat is a transient phenomenon." -Thermodynamics, G. J. V. Wylen, John Wiley & Sons, 1960
1:40 you basically gotta put in the work, put in the hours and take whats ours.
Is entropy change positive between the evaporator and condenser?
good
You never said the entropy of the universe tends to a maximum. How can you forget that?
Is this entropy of system plus surrounding or just the entropy of system
Please which law determines whether a reaction is spontaneous
a) Isn't it similar to say that the system naturally tends to a go to a state of equilibrium?, but that is predictable which is the opposite of saying that entropy=unpredictability.
I have the same doubt.. it is natural for a system to reach equilibrium which is in order rather than disorder
but aren't hot stuff more disorder than cold stuff on the molecular and atomic level? or am i missing something
If u have an endothermic reaction (delta H is positive) like H2 + I2 --> 2HI can you say whether the entropy rises or decreases and whether the reaction could be spontaneous?
The more concentrated molecule the less entropy. So the equation that you gave has less entropy. And also the reaction is spontaneous because normaly elements binds without energy input. ( as i guess)
What happened to the pan? Is it spontaneous or not?
so when you open a door from an airconditioned room, is the cold leaves/moves out or is it the heat comes in?
Heat flows from high to low temp
Heat from outdoor comes in
Which is why we always want our doors closed during the summer so we don't let the room get warm again
Another example would be how your cooling system works on a car, or the air conditioning system works on your car.
In this case cold bulk of air leaves the room through convection but here conduction is being discussed so yeah there's that... :)
anyone knows the name of the tutor? or his social accounts? please let me know
What refers to ∆S ??
Hami creation the change in entropy
Change in entropy
Now, this video destroys Atheism entirely. 🤣
"There's no order out of disorder."
-The greatest tutor of all time
haha. BTW SG-, have you become a flat earther yet?
How does the ball flow?
magic
Quantum tunneling
Cool
So, what are the odds that a structure during progressive collapse could maintain a level floor by floor failure of each and every structurally sound floor below?
if you use thermate on every structural column and accurately detonate the charges with millisecond synchronization the odds may be very good
1:24
What about life creating life
If the entropy of the universe is always increasing how did evolution defy the second law of entropy?
Its important to realise that the law applies to isolated systems. Evolution did not defy the law, as it was only able to achieve what it did with the help of a constant source of energy in the form of our Sun.
If you look at our Solar System as a whole, you will see how the 2nd law of thermodynamics applies.
@@adamhanzlik8650 if there is a vacuum between earth and sun how can the sun's heat each rearth since vacuums don't transfer heat?
Entropy is not increasing. It only does from human perception
So in other words evolution violates the law of entropy. Same with space, it is impossible to have a pressurized system adjacent to a vacuum.
I like real life examples.
hi utilizator, have you become a flat earther yet?
@@flat-earther I do not understand what are you talking about.
@@utilizator1701 utilizator well we were all lied to when we were taught that the earth is a ball flying in a vacuum
@@flat-eartherTrue. Maybe this is why entropy is not taught/ explained in school like in the video. Its premature to derive life conclusion from it.
Oh wow
Wow 😲😳
you are best teacher but most of the time i cant hear ya cuz ya whisper never raise yo sound plz change dat cuz I want yo class badly

is it chem thermoD...??
Yes

Pump?
II Law of Thermodynamics refers to everything and is absolutely the most important law in physics. It fact it is Newton's Laws of Motion as it is kinetic motion of molecules. The very basic one will be vibration. If we sink into atomic level we can even say to electromagnetic field of electron shells because this the only space of contact. Proven in every possible way. Nevertheless, the modern accepted astrophysics is so wrong with this law. Quantum physics also can't handle this law correctly. But at our human scale this law is so damn horribly true at every instance.
Ball natural
Some one tell me pls his account or anything can contact with:( i have an exam and don’t know anything and need help 🙏🏻🙏🏻🙏🏻
Natural? Systems tending science
Who is this man please? I need his full face video
Why a interject an implicated mead for a. Reverse process? In a talk of physics that attempts to exclude the nature? And god
Astrophysics is order
What are you even saying?
Msa
Sksks
Greater than zero implies astrophysical and natural science etc. So youve included in a closed state all time and universe
Bro needs to know how a refrigerator works😂 lol pumping air out(a refrigerator is supposed to isolated to keep the products cool) Go leave your fridge open for an hour and c what happens to the cooling panel
Bro is whispering
you lowkey sound like justin bieber
Ugh! Very strained explanation! Good try. Missed the mark
I made this video so even Al Gore could understand ... ua-cam.com/video/Y-UFMnuZnn8/v-deo.html
He don't need your opinion sir✨
@@MiKi-ki9fi He doesn't. Others who may spend 4 minutes of their lives may choose to do something different, no?
His voice is so irritating

man this man saves life
Some focus on the moon others on the finger pointing at the moon 😅
Ohhhh that’s why back of the fridge is so hot!
