28:16 deodrant feel colder on skin because deo is filled adiabatically in its bottle and in order to aply deo we push the pump or button due to which deo(in gaseous form) do work (work mean bottle se bahar ana) and as here work in adi in Done by gas at Q=0 internal energy is used to do work hence internal energy decrease due to which temp decrease and it fell colder on skin
I think I can put it better into words: Spraying of deodrant is an adiabatic process. So ∆Q = 0. When you press the pump, the liquid molecules expand, doing some work which is positive, so internal energy decreases. When it reaches your skin, it absorbs heat from your skin and gains internal energy, hence making your skin cooler (Original credits to you).
Answer to your question... In deo there is no heat exchange hence ∆Q=0 so acc to 1st law of thermo i.e Q=U+W , Q=0 therefore , W= -∆U since internal energy is negative it means temperature is decreasing which means coldness increases....
28:54 It’s a sudden process (so adiabatic) and when sprayed the volume of gas increases which means positive work done (i.e work done by the system). So in this process (adiabatic expansion) if W is positive then T’
Sir u are really awesome....my all concepts which were previouly done in class 11 are quickly revised through your awesome mind maps ....thnk u sir ❤❤❤❤❤❤
Sir work done in cyclic process There is graph of vp of acw is postive But i think so the signs are in clockwise direction..so i need some help in this ques🫠
This session is again very helpful and precise. I have completed revision of many chapters from this mind map series... Thanks for posting this especially for physics. God bless you and your family sir ❤😊

Sir aap ne sahi time pe video daal ke man khush kar diya thanks you sir
Kyo bhala
Sach me thermodynamics search karte hi ye video dikh gya
Kal DLP me aa raha hain

Undoubtedly the best video lecture for revision .... Thank you SIR
Precised, Compressed, To the point Mind Maps & Best Delivery. Dhanyewaad Sir. 😌❣
Sir u are really awesome....my all concepts which were previouly done in class 11 are quickly revised through your awesome mind maps ....thnk u sir ❤❤❤❤❤❤
Best lecture on whole UA-cam for thermodynamics ❤❤😊
Dil me junoon hoslo me udaan chalo krte heh thermo ka revision leke prabhu ka naam❤❤
Best one shot for thermodynamics ever , Thankyou sir ❤
The Intro of Sir was Epic(Hello Bacchaparty to Kya halchal hai ap sabka 😂)
बहुत बेहतरीन सर ❤❤🔥🔥
Thankyou sir very nice revision series'....and mind map amazing sir .... once Again thank's alot ❤..
28:48 - Surface Tension

Better than mr sir😅
Right
Confuse kar dete he mr sir and mostly jee ke sawal karake moral down 😢
Yess bro
tabhi toh air 1 mr sir laate hai tumhari aukaat ke bahar hai
@@vyapakmahawar2469bhai sir ka name jayada hai to sabhi bacche unse padhate hai.❤
@@ashutoshprajapati1726 bhai tera highest kitta aya tha test me
Temp dec of deu bcoz of
Charles law V~T
So volume of spraying pore is less that's why temperature is also low

21:29 negative
Sir.. just wow.. darun ....❤
Thank you sir all concept are crystal clear ap bhut acha pdata ho sir 🙏🙏🙏🙏🙏❤❤❤
Best explanation ❤❤❤❤
Sir sach me ek baat btaae bahut mehant kar rho ho aap a lot of thanks sir Jo chij hme samjh nahi aai thi wo samjh aane lagi
Sach me yar chapter ka pura ka pura content cover ho gya mza hi aa gya ..
Thank you so much sir ❤
Loved itt .... thank you sir ❤❤
Sir kya hi samjhaye doubt kuch rha hi nhi, Mast tha explanation ❤❤
Good to see you sr here 💕💕💕💕
Lovely and fruitful lecture ❤
Sir please make this type of one shot video of all the chapters of 11 and 12
28:47 in adiabatic expansion heat temperature decreaaes
Thank you so much Sir ❤️💓💓💓
Maja aa gaya❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
1= isobaric, 2=isothermal, 3=adiabatic, 4=isochoric workdone maximum in compression
i think he is is underrated teacher his teaching skills , easy notes all are for me very usefull
Thanks sir....well explained🙏
28:16 Due to Adiabatic process ❤️
THE BEST EXPLANATION OF THERMODYNAMICS IN THE SIMPLEST MANNER...........THANK YOU SO MUCH SIR
❤❤ superb lecture sir ji , aapki mehnat ko dil se salute hai 🙌🏻
21:28 work done will be negative as the volume decrease.
These are really absolutely fantastic sirrr❤
Excellent sir 😊
Sirrrr ❤❤❤❤❤
Ur the best ❤❤❤❤❤❤
very good lecture and awesome notes
Very very beneficial......❤

Thank u sir ❤❤❤❤
Sir 1:05:25 me 4 me Adibatic compression hoga
yes
God bless u sir 😊
Thanku soo much sir really a awsome mind maps sir

Thank you so much sir
one of the best lecture
you are a great teacher
Thank you
1=isochoric, 2= isothermal, 3=adiabatic, 4= isobaric when eork done maximum
Sir work done in cyclic process
There is graph of vp of acw is postive
But i think so the signs are in clockwise direction..so i need some help in this ques🫠
Thank you so muchh sir it's very beneficial for us ❤
Thank You So Much Sir you helped me alot ❤😊 Tommorow is my exam
Loved it ❤❤
Yes sir good mujhe bhut samajh me aagaya❤❤❤❤
Adiabatic expansion is cooling effect
❤❤nice sir good explanation
wonder full teaching ❤❤❤
Such a great mindmap.. thank you sir!
Very helpful video sir ❤️

Osm rivision tha sir thank you so much ❤
Sir genuinely mind map bohat sahi hai and kya hi time pe yeh vedio banayi hai 🙇🙇 and your teaching skills 🙌🏻🙌🏻
Work done negative due volume decrease
Thank you so much sir!!!❤😢
Helpfulllllllll❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
Best video ❤❤❤
