2nd Law of thermodynamics - Principles of Refrigeration

[@oktay2]

What my prof couldn't achieve with several hours of lessons, this guy did in just 8 min. A very big thumb up :) 👍

[@HoraceMash]

By far the best explanation of heat pumping and refrigeration that I have ever seen. Your powers of communication are awesome!

[@jsmith7348]

holy shit it is

[@being_medico_]

This is what I was searching for 🎉🎉❤ .... As a NEET aspirant , from NCERT book the topic was not clear to me , then I searching the topic and got it , it's outstanding.. really.... Especially you started the concept with that first simple example, from that it being so easy to understand later actual refrigerator... Tnx ❤

[@kawitathapa1031]

this video is so underrated!!! so beautifully explained

[@salazarslytherin36]

Definitely one of the best tutorials I've ever seen in KZbin! Thanks for the video!

[@JarredDavidson]

I study physics because it excites me that everything can be broken up into simple first principles. This is a perfect illustration of just that.

[@theinglorious1569]

This channel deserves much more subscribers.From here we get Quality contents that are really helpful and informative. Thanks to them.

[@koduribhavana7070]

The best vedio on KZbin. The concept of heat pump and refrigerator is well explained. Thank you for the amzing vedio.

[@nikitagorkovets4336]

OMG, I finally understand why refrigeration works. The principle was never explained to me.

[@ericktulay7397]

This video precisely described just what I needed! I definitely commend the concise explanation! Cheers to teaching science exceptionally!!!

[@nupurpandey9072]

Awesomee explanation!! Especially that thing when you told we can't keep our refrigerator open and expect our room to cool down

[@gauranshbansal8915]

Thankyou, you cleared something very particular, which sadly no one till now was able to.

[@sweatyredbull]

I went through undergrad and have a much better understanding of refrigeration just from this one video. Thank you

[@coolazyy]

bro i cant take you enough for this explanation i need it

[@ThisIsMonkeyy]

Thank you for this! What seemed incredibly difficult to understand from reading a text book, was in fact easy to learn from your video.

[@elibenaron]

Didn't expect it to be this good.

[@vilaadnewman5943]

This is godsend video by far so good explanation clear and smooth

[@juliangarcia4876]

Just got a smack on the back of head with a awesome lesson thanks

[@agillings40]

Awesome! Best video that explains 2nd law of thermodynamics

[@dobythedog]

Absolutely brilliant explanation of refrigeration principles.

[@imashfernando9751]

what a video !!!!! short & sweet ! thank you sir !!!!

[@benwilms3942]

Great explanation, they way you say refigeratior.... killed me.

[@shatakshigoswami4072]

So precise and wonderfully explained!!!!

[@jidendrap3745]

excellent explanation...loved it

[@alarissacamila]

amazing video! the best explanation on this topic on youtube!!

[@prabhatprabhakar10]

GOD bless you thank you so much u made it finally understandable to me after lot of research on you tube and google chrome. And i don’t know why am hating my teachers who made it so confusing and I wasted my time.

[@otacilioribeiro8944]

just beautiful, exactly what i was looking for

[@SunilKumar-zs5vh]

very nice explanation

[@mklik4]

Thank you for this phenomenal video!

[@nandun911]

Well explained! Thank you❤

[@arbazbagwan51]

Best✨

[@AnshikaYadav-jp1cr]

best explanation thank you

[@achalgupta8053]

Awesome explained sir thank you 😍😊

[@ForDreamsThatDoComeTrue]

A nice intiative......keep going..... May you people acheive great heights....

[@harshmeena9655]

Love from India🇮🇳🇮🇳

[@harshmeena9655]

Very nice explanation

[@ajits1530]

Thanks for explaining it so beautifully

[@srirajkumar4891]

Cool 👏👏👏😊👌

[@MCurian]

Super explanation

[@nitrogen-]

Super lecture

[@ANONYMOUS-cw5tx]

5:14 the key point 👍 6:22 heater and heat pump it's not the same 👍

[@cosmic770]

Very helpful for my class 11

[@sand_particle]

very nice....

[@36haroonfarooq44]

Realy helpfull☺thanks

[@allindiavinesandmusic8953]

Nice and really helpful

[@spal3907]

very very good explanation .thanks a lot man

[@Simon-dm8zv]

2:06 Why is it possible to extract more energy from the room than it took to compress the refrigerent?

[@leeweatherly9673]

It's really helpful. A BIG THANKS!!!:)

[@atulkaushik2350]

LEE WEATHERLY

[@forrestalthaus3292]

Great video!

[@JohnnyJr396]

Thanks! Is the the transfer of heat entropy?

[@natisita1525]

Tank you very..... much

[@sureshv9377]

Without the compressor by heating which gas can we use?

[@victor7530]

Thanks for the information.

[@staciwhite6263]

This was a great video and explanation!! I'd like to ask what animation software you used to create this teaching tool. Thanks.

[@gelomelo3426]

Hi. Sir pls explain more about bonus heat. What's bonus heat? Where it comes from? What does bonus heat mean? Thank you.

[@starlorddidnofingwrong9008]

thank you

[@PranabSwSahoo]

Thank u so much sir❤️

[@skkuedu]

The video starts with "In the previous lesson...." Where is this previous lesson? Is it also on KZbin?

[@davidphy]

Thanks, this is a very good video, sincerely I liked it, it's very usefull.

[@princeoftheblues]

The ball bouncing spontaneously does violate conservation of energy: if you catch it, you have something for nothing. If you want to see the second law violated, please watch "Second Law of Thermodynamics broken, violated. Try it yourself" I wish this presenter would also see this. And, for all of you students, please tell your professors.

[@bhagathkittu3421]

Super

[@WalkinBeauty278]

Entropy...2nd law....Climate catastrophe results from trying to use refrigerator to cool room with the door open....we allow all the waste heat back into the room

[@atwtmvtvftwsgavralps]

live laugh love godkin, but this was very helpful

[@ameerhamza4816]

So heat pump are more efficient

[@KeshavJadhav]

Yes, COP of Heat Pump = COP of refrigerator + 1

[@titirmajumdar3730]

good

[@koustube4167]

After you compress the Pump and Leave your hand there is decrese in internal energy ..... Why ?? why does piston come up ?

[@vincentweiss3216]

Technically, the piston shouldn't rise to its original height, but adiabatic expansion will cool the gas down as it decompresses. Basically, the work required to compress the gas is greater than the work needed to lift the piston back up. The lost energy accounts for the cooling effect. This happens because the relationship between volume and temperature is linear whereas the relationship between volume and pressure is nonlinear. All this means is that when the gas is compressed, most of the energy will be used to increase the pressure while some is used to increase the temperature. Likewise, when the gas decompresses, most of the work comes from decreasing pressure and some from decreasing temperature.

[@DY-cq3qd]

He doesn't explain that heat(energy) AKA latent heat, is not really the same as temperature. Physics for people who already understand physics.

[@leokovacic707]

How does spontaneous basketball bouncing not violate every law in the book?

[@benvolino6604]

Where my Kozak squad at

[@mdizzle7742]

You definitely mean condenser. You are the reason I make more money than you based off this video 😂

[@tymchanneltv1143]

good
