Heat can not be fully converted to work. That is why heat is called a low grade energy and work is called high grade. For more detailed explanation you can visit my channel, I have explained the second law of T.D. and also given the explanation about heat and work.

Thank you sir for your
effective lecture in less time. This is what we all students are searching for......
massive love from PHYSICS student from PAKISTAN ....
@@vinaysawant3859 why bro
Sir nice teaching ...convenient not too much dragging and easy
Amaazing..shorttime lecture..and clear great concept...
Thank you sir for your
effective lecture in less time.❤
Super explainatoin satisfied sir
Hi
Appreciating u sir ,vry nice video ,im satisfy from tbis video and heat engine thanku thanku vry mucb
This was super simplified and easy to understand, Thankyou!
Please Sir tell me why we call heat as low grate energy and work high grate energy

Also for more elaborate explanation of heat engine you can also find that video on my channel.
Superb video..sirji
Great explaination in less time
Superb lecture. Thank you very much sir ❤️
Excellent
Nice lacture
Anf thank you sir🙏🏼
Best lecture ever.
OP👍👍👍👍
This was good. Thank you!
I just scratched my phone to remove the fly
Mee too
Sir you teach impressively
4:34 Sir is the QH is directly proportional to QL? If we increase Heat from source then heat will be rejected more right??
Nice explanation
Best
Great teaching sir...
Tq sir simple explanation
So nice 👍👏
QL is actually Heat Rejected To Heat Sink From Heat Engine.
Sir if sink is less then room temperature then engine will work on the heat already in the universe as entropy
ggoood
Thank you so much Sir
to reject the heat there must be a workdone on the system, i.e., workdone to the pump. so Wnet becomes (Wout - Win)
Nice lecture
thanks sir and v nice
On which principle a heat engine is works..?
Thank you man
Thank you sir
Absolute God
How to separate real system and surrounding in this case
The engine is system while every thing around it , is its surrounding
Thanku
tq sir
Thanks so much
Sir is direct heat engine is simple heat engine?
nyc
a very nice
thankyou sir!!
Thank you sir
