6:43 how can body of T temperature absorb radiated heat from body of T' temperature? If T > T' . Or this temperature dependent heat transfer is only for conduction and convection , and not for radiation? Like any body can radiate which can be absorbed by any body irrespective of temperature. But if T'> T, H becomes negative. So heat loss becomes heat gained. Right?
Then the main body radiates heat and transfers it to the environment outside. And the outside environment also radiates heat,which is got by the main body. This process goes on... according to prevost's theory
At 9:04 we considered there sigma. So does it means that we are considering the surrounding as black body because value of sigma is only valid for black body.
Sir , what is the reason behind taking the fourth power of absolute temperature and not only T in this equation and one more question , what is the fourth power of kelvin and why the H is directly proportional to T^4 and not to T?
Sir i have a doubt Why u take emmisivity of surrounding 1 in case of black body And in case of ordinary body The emmisivity of both system and surrounding is sigma Why same ? (My confusion is the emmisivity of system and surrounding may be different ) .
Sir plZ ek lecture physics ke concept ke uper bana dijiye ki physics ko kaise visualise kare aur kaise usko samjhe ki physics master kaise kare plZ sir aapki ati Mahar kripa hogi 🙏 Very very very infinite kind of you sir 💯😊
If someone can break the complex things into simpler, then that is really appreciated. You did exactly same.
Super Sir...lot of respect for your teaching..🙏

best u tube physics videos
Thank you sir for better explanation
Really sir at one side , arjit singh is my favorite singer and at other hand you( arjit daripa) are my favourite teacher
Thankyou arjit
Ol*.
Really impressed with ur way of teaching
Kmaal ki videos hai sir apki.pls make video on Eternally collapsing objects🙏
Great ,this is which i wanted for jee adv.❤
Sir aapki wajah se hi physics mera favorite subject h
Many thanks for your dedication and providing indepth understanding of concepts
Very good expalination 💗
Very nice video sirji
WHICH SOFTWARE YOU USE FOR TEACHING SIR...PLZZ REPLY SIR PLZZZ
Literally amazing video 📸👌🏻👌🏻🔥🔥🔥🔥🔥🔥🔥 outstanding explanation 👏🏻👌🏻👌🏻😄
Sir aapki aawaj me jadu hai
Very kind of you sir 💯
I am from assam... I like your video too much sir..... Love you sir😘😘😘😘
Superb sir.
Great explation sir but i have a doubt Sir when surrounding temperature is greater that the body temperature for that how we deal

@@Sourja got it thnx👍
Superb sir i really understand everything
Sir your is very impressed and helpfull
Bcs of your drawing
You are fabulous sir...😍
Sir please make a series on general theory of relativity and twin paradox
Thank you sir 😁😁😁
Always be happy 😝😝😝
Crystal clear concept
Sound quality bhot aache hai sir 💝💝💝
Thankyou very much sir for this best educational videos on edupoint channel
Well explained
veryy impressive video sir about boltzman law
Thanks❤️I really appreciate your help...
This really helps❣️❣️
Sir, please make a video on Unruh effect.
Bhai vo bhut high level ho jta h
Thank you so much Sir.
Your explanation is superb.👌👌👌👌👌.
You just cleared all my doubts.😊
Please make video's for bsc physics hons
sir please bateye app padhane ke liye kon sa app use karte hai
Congratulations for 1million
Love you sir ...
Thanks sir!!
No one has described black body the way you have described
As I had listen many lectures
Sir you are using black background is very nice 👌 it doesn't irritating eyes
Thank you very much
I enjoyed your video .Please make more videos.
Amazing sir
Love from m.p ❤️
Love from U.P
U r too good sir.
Sir please make a video on Boltzmann brain
Sir, what is the difference between Stefan's constant and Stefan Boltzmann constant
At 9:04 we considered there sigma. So does it means that we are considering the surrounding as black body because value of sigma is only valid for black body.
thank you very much sir.
Sir refinery par video upload kro jese cracking reforming thermal cracking ect. Thnks
Sir , what is the reason behind taking the fourth power of absolute temperature and not only T in this equation and one more question , what is the fourth power of kelvin and why the H is directly proportional to T^4 and not to T?
Because if there is T^4 change in temp.
There is unit change in H
Waaaaaaaaaahhhhh hame to ye pta hi nahi tha@@santoshsharma5974
Thank you sir . :))
Bsc 3rd year ka bhi pda dijiye, app bhut achha pdate hai sir ji
Sir please bsc physics pr video banaiye na
Thank you so much for this video sir ....dear sir pls provide lecture on NANO MATERIALS...
Sir i have a doubt
Why u take emmisivity of surrounding 1 in case of black body
And in case of ordinary body
The emmisivity of both system and surrounding is sigma
Why same ?
(My confusion is the emmisivity of system and surrounding may be different ) .
Sir plZ ek lecture physics ke concept ke uper bana dijiye ki physics ko kaise visualise kare aur kaise usko samjhe ki physics master kaise kare plZ sir aapki ati Mahar kripa hogi 🙏
Very very very infinite kind of you sir 💯😊
Sir why is it -4, -8, -1.... Like this all in given formula
Great sir
Thanks
Sir aapko 2,3 questions bhi karwaane chaiye.......#justsuggestion
You are god for those children who don't afford tution
Very nice 👌👌👌
What is the emesivity of white colour surface
Please upload more videos of chemistry of 11
Thanks sir
It should be directly proportional to time
Nice sir
Love u sir
Lovee ittt sirr superbbb respectttttt 🙏 🫡 🤲 🙌
Upload more videos sir🤗🤗
Goooooooooooooooood Videeeeoooooooooo
why T power 4 sir?
Sir 12 th kab start hoga
Good
🔥🔥🔥🔥🔥🔥
Unable to dislike the video❤️🩹
Sir
i mailed you just before plz help me to do that problem!!
One thing you said is wrong!!!
Blackbody is not a good radiator
Sir clear my doubt...plz
Tell me
🔥🔥🔥🔥
Sir your video screen is also black body 😅😅😅😅😅😂😂😂
Face reveal 1m pe karo ge kya sir
Sir 12th kab start hoga
Jald hi....
@@edupoint.physics ok sir
👍👍👍👍
You can try to change translate to another language tamil please iam so sorry
Thanks sir
Sir 12th kab start hoga
Sir 12th kab start hoga
