During my school or college days,we missed this type of lectures..very nice explanation and no chance of asking doubts bcz he reads the mind of students and giving proper explanation with examples..thus is called quality of teaching..
And so my professor graduated from MIT, and got a lot of stuff on nuclear engineering and worked at nasa, he even has contributed to many things in science and guess what? he doesn't explain as good as you, what does that mean? Yes we all may be different, but if you can explain something well and make it look so easy, I believe you Sr. have a brillaint mind to be admired. Thank you for your videos. In behalf of all the viwers that are trying to survive during these school times, we appreciate your fanstantic work. I hope you are a father of manny children !!
Sir hats off to you, till now I was very confused that why the heat is being rejected. But after watching this, I got it. You explain the complex concepts by giving simpler examples of PHYSICS. Thank you so much sir for coming on TH-cam.
Wonderful to see you on this 'Tutorial Point' platform as I used to access your tutorial videos on another site in the past. Thank you for being a patient teacher.
Hello students, I tried to explain some very important concept in this topic and the difference between heat engine, heat pump and refrigerator.which are very useful for neet and iit-jee. I am sure after watching video you will be confident in the topic. Here is the link th-cam.com/video/VzGyccrI-zI/w-d-xo.html
sir where are you right now i dont know.. wherever you are you always be happy.. such a great teacher i have never seen in my life.. you r God to me.. really want to bow down to your feet sir.. we miss you alot
If you don't have a coolant, the energy and therefore temperature difference between expanding gas and container ( chamber) will reduce because the heat is not rejected to allow container to cool down after previous expantions, which decreases efficiency.you have to think of the container as part of the sink
This is something you need to understand before solving problems..see he just made me realize that the quantisation principles are involved in the heat engine.
let's say the temperature of air outside is 308 Kelvin. The temperature of an engine is 873 Kelvin. Does it mean that the efficiency of this engine is 1 - 308/873 = 64.7 % ?
@@jakomuya6444 thank you for the reply Daniel. However this is not the efficiency of an engine with the given temperatures. This is what is known as the highest possible efficiency that this engine can deliver. In other words, this means that 64.7% is the maximum possible efficiency of such an engine. In reality it has to be less than 64.7% (somewhere close to 15%) otherwise it violates the laws of thermodynamics.
Your explanation of reservoir and sink that thier temperature wouldn’t change is no longer true. Unfortunately high numbers of inefficient engine has raised our Earth’s Temperature and its quality

absolutely bro. in school times, our teacher haven't taught us in this way. they are only cramming us.
And so my professor graduated from MIT, and got a lot of stuff on nuclear engineering and worked at nasa, he even has contributed to many things in science and guess what? he doesn't explain as good as you, what does that mean?

Sir, after every video can give a side to take a screenshot
Wonderful to see you on this 'Tutorial Point' platform as I used to access your tutorial videos on another site in the past. Thank you for being a patient teacher.
Sir someone commented that pradeep sir was Rip? Is it true?
16:40 sir your analogy is great ....
seen many videos of heat engine,, but this is best lecture ever seen
Sir, my studying efficiency has now been increased due to your teaching sir.
Thanks sir
We appreciate your efforts.
Hoping you will come up with more interesting topic.
Great explanation sir🤩
Amazing explanation ❤
sir very nice teaching. Sir you are the best physics teacher i have ever seen in my life.
Thank u sir fr d best explanation. U gave me extra information and cleared all my doubts. Thanks a lot.
Great sir every small concept is clear now thanks allot sir
Very nice description; thanks alot!!
Thank you very much sir for this wonderful teaching. I easily understood the concept sir.
Great 😊
Teaching technology
Very conceptual and interesting sir. My interest is growing in Thermodynamics because of yout teaching techniques. Thank a lot.
Good job sir 👍👍👍👍👍
fabulous sir its very useful,thank you sir
Thanks for this nice, clean explanation😍
Awesome
I love the way you teach Everything retains in my mind

Just wow...thanks from Bangladesh
Thanks.
Amazing the process of nature
I can only say. ....Great.
Great explanation sir🙏
Super explanation thanks Sir
Excellent lecture..Worth appreciating
sir where are you right now i dont know..
wherever you are you always be happy..
such a great teacher i have never seen in my life..
you r God to me..
really want to bow down to your feet sir..
we miss you alot
thank you sir from sri lanka
Great class Sir
speechless ..u r great sir
Very clear teaching - tanx prof.
Sir your video are really much helpful after watching I can to teach like an you sir ,so really thank you sir.
Best😊
Thank you so much sir 😊 Amazing lecture ❤
Sir why it is necessary to reject Q2 heat
sir nice explanation
Superb explanation
Very nice explanation sir
thank you for the good explanation.
Thank u so much sir for help us🙏🙏
Watch it in an increased speed of 1.25x
Tips for students..
Thanks you sir nw I understand 🥰🥰
I like the way u teaching sir
Very good explanation
Excellent
Sr thankyou so much
i can study like this whole day
very nice sir
Excellent explanation.Thank you sirr..
Always remain in 💜🙏
Very nice
Osm sir nd thnk u 😊
Superb lecture
Thank you very much!!
very useful sir, thank you
Thank you sir
Sir,cold weather me effeciency more. Please comment....
Baljeet Yadav pressure decrese ho jata hai
Nice sir
So sir make more and more videos in physics. Please
Thanks sir u explain very well
Nice sir ji
Whether the piston is the working substance ???
Sir then why do we have coolant to cool the engine,we're it is more efficient when it is hot.
If you don't have a coolant, the energy and therefore temperature difference between expanding gas and container ( chamber) will reduce because the heat is not rejected to allow container to cool down after previous expantions, which decreases efficiency.you have to think of the container as part of the sink
Sir I thing you make video about diatomic gases rigid rotator.
Tq very much sir.
👍👍👍
in the formula ,
n=1-t2/t1......difference of the temperature should be taken...........then by that delta t1 will be greater and hence n decrease
Wonderful job done by you sir... your lectures are so helpful.
Thanks for such kind of explanations of the lecturers with various examples.
Nyc sr
super sir
sir you explained very well... but sorry to say this not sufficient to solve the numerical problems.
This is something you need to understand before solving problems..see he just made me realize that the quantisation principles are involved in the heat engine.
is channel par add nahi aate hai shayad
Pratyush Pandey ati ha
Sir plz say more about heat engine
Awesome but I kept my playback speed at 1.5x😂😂😂
Watch at 1.75x
Talha-373 bs mathematics second semester Evening
let's say the temperature of air outside is 308 Kelvin.
The temperature of an engine is 873 Kelvin.
Does it mean that the efficiency of this engine is 1 - 308/873 = 64.7 % ?
Yes which is 0.647. Still less than 1.
@@jakomuya6444 thank you for the reply Daniel. However this is not the efficiency of an engine with the given temperatures.
