The work is done by the gas at the cost of internal energy so that there is fall in temperature also we know that the internal energy depends on the temperature
sir ,du=Cv dT ye to constant volume me hota he . to ye equation adiabetic process me kaise use hoga ?? adiabetic process me to volume increase hota he...please explain me..
@@ullasrajs3537 Volume will be constant because no work is done...no transfer of heat so particles will not get k.E to move...so volume will be constant......
Koi thermodynamic system meh adibatic process karyane se pehele hi uska, internal energy hota hai. ham system ka volume constant rakh ke usme heat supply garte hain tab uska internal energy badta hain iska matlab uska internal energy sirf tempreture ka function at const volume hain. Ish liya hamne du=Cvdt lekha hain. Yeh adiabatic process se pehele jo internal energy hain, uska equivalence hain, in terms of cv and dt. second term hain, pdv, meh constant volume nahi liya gaya hain, kuin ki jab tempreture ghategi, to internal energy ghategi, uski bajhe se system meh work done hoga, uske volume badega. (internal energy du= cvdt is transferd to mechanical work, pdv). Yeh volume change, aur uper ki constant volume alag alag process ko describe karti hain. Ishiliya confusion hogaya hoga.
Hello fawad mirza ! Thank you very much for the support you have shown. Yes! I missed that. I shall keep your suggestion in mind. And as always ...... thanks for watching.
Totally fraud , in first equation , you are calculating dU = Cv dT for constant volume system and at 11:15 you are equating it to to dW for constant pressure system. Please reply if you have any explanation about your stupid approach.
Helllo Kristen, This is "stupid approach" here. Bhai aapko Cv aur Cp ek equation me laana hai. Thik hai ya nahi? Cv kahan se aayega? You need to have a system with constant volume. Cp kahan se aayega? You need to have a system with constant pressure. Agar aap Cp ko constant-volume system se laa sakte hain to congratulations dost! You say, Mayer's formula is there Cp - Cv = R. Par wo bhi to isi "Fraud" aur "Stupid" approach se aaya hai. Jo bhi ho absolute truth to kisiko pata nahi hai. Ho sakta hai ki aap hi iss "fraud" aur "stupidity" ka parda faas karein. "So, how would you prove poisson's law?" - Who the hell I am to prove that. It has been proved by Poisson in this manner. Aapne iss approach ko "stupid" kaha kyunki kitaabo me jo likha hai use details me ek ek karke maine samjhaya hai. Varna kitab me to sirf formula hai. Use log details me samajhte nahi hai aur doubt bhi nahi aata. Par kitabo hai to yahi. "Sometimes good enough is not good enough." Regards- The stupid man expecting a little amount of respect for his work.
EduPoint Bro don't get sentimental. I analysed the given case as well as Meyer's formula many times and came to realise what you are doing is RIGHT. the truth lies vehind the fact that ENTHALPY IS A STATE FUNCTION. Though these are two different situations but we can substitute dU just because change in internal energy is same in both the cases and it is independent of the PATH followed. Here dU acts just like a normal function of temperature Like dU= 3t-8 Here Cv is a constant and acts like the 3 in above equation. I apologise for my harsh comments. But I want you to FEEL as well as UNDERSTAND that your explaination as well a meyer's proof is absolutely right . Your accepting that there is a flaw in the proof is wrong. YOUR PROOF IS RIGHT . YOU SHOULD FEEL THIS.Truly fifteen minutes ago when i realized this phenomenon i was jumping with excitement of enlightenment. Please reply if yyou understood what i explained above.You can also improve your video just by putting a sentence that enthalpy is a state function. Again , Sorry for the harsh comment. YOU WERE RIGHT. I REQUEST YOU TO UNDERSTAND MY EXPLANATION Regards Kristen Lover

Sirji constant Volume wali internal energy Adiabatic process mein kaise use ki ?
Yahi question pooche me bhi aaya hu sirji,,,
The work is done by the gas at the cost of internal energy so that there is fall in temperature also we know that the internal energy depends on the temperature
@@anshawasthi4185thanks for reply🙏🏻
But i remember a little about the topic because I asked a year back 😄 😊
Super sir you are my real Superhero
wow sir amazing explanation. 👍👍🙏🙏
Best teaching I have ever seen
sir ,du=Cv dT ye to constant volume me hota he . to ye equation adiabetic process me kaise use hoga ?? adiabetic process me to volume increase hota he...please explain me..
*Exactly same problem I have* !
@@SimSimSimSim 🤔🤔achha not seeming appropriate .. I couldn't understand 😐😐
Adiabatic process mein heat transfer zero hoga..so volume constant rahegi.. internal energy
Volume is not constant in Adiabatic process.
The reason dU=nCvdT
Cv is taken because internal energy is not path dependent.
@@ullasrajs3537 Volume will be constant because no work is done...no transfer of heat so particles will not get k.E to move...so volume will be constant......
This lectures is also for b.sc chemistry students
Namaste sir, from West Bengal .
Sir in the above case when the process adiabatic then how can take dq=dU and then put CV=dU/dt

You are awesome 😎😎👍
Best physics videos
Nice. Better if you explained a quick application of that formula.
Hello fawad mirza !
Thank you very much for the support you have shown.
Yes! I missed that. I shall keep your suggestion in mind.
And as always ...... thanks for watching.
Application is that it can be used to find work done in adiabatic process
During expansion the internal pressure given by the system must be less but you considered same
Sir one question ... If you don't give any heat to the system .. then how piston moves upward..
The gas uses its internal energy to do work, and pushes the piston up
If friction removed bt piston and wall
Sir ek doubt h ye constant volume se du ki jo value ayi use adiabatic me kaise put kiya gaya please reply sir
Thanks sir muze aaaispar bhaut doubt te Sab clear ho gaye
ham ne 1k alag thermodynamic system se kyu cv nikala or usko adiabatic system ka equation Mai kyu put kya
Rest In Peace excellent question, I am also thinking about this!
@@SimSimSimSim
How in adiabatic process we bring change in internal energy of system by considering piston moves upward s of its own
Thank u it was very helpful
Sir thank u soooo much... Much needed video...
Sir bsc physics ka jitna ho sake lecture upload karna.. Plzzz 😶🙏❤
Thanks u sir... Respct for you❤🙏
Thank you very much 🥰💖
Lekin adabetic system main heat kaise Diya yea badme bataunga bolke batayahi nehi, Aisa kaise
Sir dU=Cvdt kyu hota h yha pe???
Adiabatic process mei volume constant to nhi hota h!!,
Sir please reply...... 🙏🙏🙏🙏🙏
Internal energy (u) depend only temprature not depend volume / pressure,etc. This is valid for ideal gas .
Sir, y did u use here natural logarithm instead of common algorithm.
Thank you sir
Why,
Pdv + VdP = RdT
(Pressure is constant)
So it should be ,
Pdv + 0 = RdT
Pressure is not constant
Thanks sir ji.
If heat given to the system is zero then how internal energy change
Ty❤
Sir dv must be zero at eqn 1 why is nt
❤️❤️❤️❤️
this is reversible adiabatic equation
Super
Thanks sir u are great
nice
sir please upload related to the communication

Ok
sir h.c verma ka solution complete dala kro

I love and accept that.
So, how would you prove poisson's law?
Helllo Kristen,

Dear Kristen,
Every comment was ironical there (what I replied to you, like “stupid”, “fraud”).
I do not have any doubt.
