Carnot Cycle and Carnot Engine

[thispageismylife]

too bad my tasks are at a complete different level of difficulty

[huzaifa129]

i would like to see such a talented professer!!!!!!!

[lilcote93]

im taking this right now with a prof that graduated from MIT as well ;)

thanks for all the help sal

[motopilot322]

You're animations are just fine man.. I've never taken formal physics courses, but for 10+ years now I've done my own research via books,magazines etc... Your videos by far are the most clear and to the point..your analogies are tough sometimes..but het..that's what pause and repay are for! Keep it up brotha! This is much appreciated!!

[dauhud]

how come 5 illiterate guys are on you-tube watching these videos.

[ninjathakur]

you have got a nice voice and understanding

but use better animations

the current one suck

[s0m0c]

Gracias.

at 10:11 Salman Could have meaned "my pressure would have kept going down and my volume would have kept going up"

[490mubeen]

Not constant volume ...I want to write constant internal energy

[490mubeen]

Upto my knowledge adiabatic process is an constant heat process not a constant volume process ,so why we keep constant internal energy in the process B...and make it zero ...?? Can anyone plz tell me..

[s0m0c]

adiabatic process means isolated, so no heat transfer can ocurr,the system travels trough an isoterm and if the temperature doesn`t change for our system, neither do the Internal energy is going to change, so is constant.

But in and adiabatic process the temperature of the system is not constant is not travelling along the isoterm anymore.

[s0m0c]

in both process the volume is changing going up during expansions and going down in a compresion

[Snelmboy]

Life saver man, I WISH you were my thermodynamics prof, wow. . .

[kashiii2011]

what do you do if it isn't a mono atomic ideal gas and if we are dealing with steam...?

[nfs66]

YOU SHOULD GET THE NEXT NOBEL PRIZE AND MY PROFESSORS SHOULD GET FIRED!

[jayjames8791]

Laws where meant to be broken.

[kludara]

Appreciate ur work!

[gazhill89]

Thanks

[jasonpunza]

all your videos are very helpful. thank you!

[TET2005]

Thank you sir. Your video is worth a million dollar instead of reading the boring physical textbook. As long the concepts are grasp properly, it will stay with you forever.

[tripleh847]

U R MY HERO! THANK YOU SO MUCH

[lalox3003]

THANK YOU SO MUCH!!!!



[ptcala99]

shitty microsoft paint-esque program + 20 minutes = lucid explanation of the Carnot cycle....amazing!!!

Thank you so much!!! I feel more comfortable with thermo than ever!

[jamiegollings]

Fell much more comfortable about my Therm exam on Monday now, thanks!

[floweriepot]

You are pretty much a 24/7 tutor of EVERYTHING. I cannot say thanks enough times!

[floweriepot]

I feel so bad just saying thanks over a comment. I want to make a speech and a facebook fanpage, and a petition for you to win some major major world prize. You are amazing. Thank you for saving my life!

[draegernaut]

THANK YOU, i understand now

[OpsOfCod]

wow i have to say this is awesome. I didnt think i would find a video that would explain carnot cycle to a point that i would understand. Thanks man !

[4kx]

you dont know how to use paint;D. However, video is helpful ;]

[tig8med]

May allah (God) give u long life to educate us

[bumapavan]

u r awesome simply superb extrodiary i need all cycles like otto,diesel,rankine.can i get mechanical engineering subjects like mos,r and ac,TD1,TD2,TD3 AND ALL SUBJECTS.all students will love u .because its really nice

[Growriginator]

Thank's from Germany!

[Growriginator]

Thank's from Germany!

[kenny9466]

muyy buenooooooooooo

[CreQ]

Our internal energy did not change? I thought pressure was kinetic energy, and if the pressure went down the internal kinetic energy went down? Just like if you removed pressure from a Co2 cartridge by firing a pellet gun, the internal energy changes and each successive pellet will fire at a slower velocity.

[hfdpayner]

thanks, i should just drop out of uni and pay my tuition fees to you!

[kingfker]

This guy is awesome!!! I gona thought out my thermo books, because it is crap!

[lxie1]

thankyou

[zpiazza]

these lectures should be put into number order

[smehtaphy]

hi...nice video.........helpful for the students

[Adaeze611]

In the future I will name by daughter adia and my son batic since we did it in isolation and energy was lost in their formation

[Oh4Chrissake]

How do we know that Q2 < Q1? That is, how do we know that a smaller amount of heat is transferred from the system, between C and D, than to it, between A and B?

[hardeep1080]

Hi, one little problem, in the final step of carnot cycle going from D-to-A (16:07) how can the process follow an isoterm? as your adding peables then it is plain compresson and during compresson the tempture should increase hence you would need an cold heat sink so the rize in temp due to compression could be lost hence maintiing an isothermal compression process

[amassad127]

All of these videos are really just incredible. I'm a sophomore engineer and I still find these videos really helpful! I wish there was some way to help you put out these videos.

Really, really admirable--thank you

[avestak]

Hi,

Love your videos, is there a way to watch just thermodynamics ones? Thank you

[mikeandino81]

So A to B is adiabatic and so is B to C? I'm sorry but isn't T2 going into the system? Or is this a system definition issue? Thanks for the video, though.  Very good!

[1stNotes]

@mikeandino81 nowp.....t2 is a cold reservoir...when we compress the system, heat is generated by the system. that heat is immediately transferred to t2..~ jz like u put a hot coffee into the fridge. heat from coffee loss into the fridge~ (n_n")v

[dnanalahcnap]

thank you....you just saved my ass

[Yami7761]

U R A HERO

[theincapable]

@TheMIkex24

He accidentally took the wrong word. The pressure is going down and the volume is going up, as you can can see in the figure.

[firerevenge]

i still don't get it

[SteroidsR4success]

I dont know about you but the main thing that was confusing me when I first watched this video was that I forgot when the volume goes down the temperature goes down, because the particles are bouncing against the walls (walls made out of other vibrating atoms) of the container more often which remember, transfers some of their kinetic energy to the particles that make up the wall. [1]

[SteroidsR4success]

This is also called friction, when particle A, hits particle B, Particle A transfers its kinetic energy to that particle B. Just for deeper intuition, the reason for this is because when particle A is moving it has some kinetic energy lets just say 1, and when it hits particle B its kinetic energy turns into 0 and that 1 ends up essential being transferred to particle B. Hope that helps. [2]

[SteroidsR4success]

And note: in this video particular, the only reason why the temperature goes down when the volume increase is because the system of all the little particles is doing work, therefore transferring its kinetic energy. So I guess the example I mentioned was something not even included with these videos and I guess I confused you even more lol, sorry.

[TheMIkex24]

Hello. As you said on 10:10 you said that the pressure it goes down and also the volume it is going down. Is that true because i think that the volume it is going up(the volume is going to be bigger from B to C). Just give me an answer to clear the things in my mind. Thank you for your help and your videos.

[nolaeast]

This is a really good video. Thanks for posting.

[afrei5]

As usual, great video Sal. You might want to also include this in your physics playlist, as my university covered Carnot cycles in Physics 2, but didn't touch on them in Chem.

[veteran25]

Good job explaining this complicated topic

[sweeteuphoria333]

enggizo, this is physical chemistry. physics+chemistry.

:)

good stuff

[malik9241]

all lectures deliverd by this HONOURABLE professor are soooooooooo nice.

i like all the lectures and enjoyed. i realy appreciate wow. keep it up sir. May God give u long life to educate us

[shootshoot]

man you're really cranking these out, it's hard to keep up

[DMZ509]

you need to watch the previous vids, you can't understand a subject without knowing the sub-subjects, especially in chemistry

[enggizo]

This is not Chemistry thats thermodynamics ..

[DMZ509]

Same thing. Thermodynamics is one of the subsubjects of chemistry, even physics.

[enggizo]

Ok . but what do you think of the explanation

I think its poor

[rosannadanicamaguad]

thermodynamics is part of chem

[YoLninYo]

Do you use the mouse or a tablet? love your work! so awesome!
