23:18 pr sir if we keep the m2 mass again after final equilibrium is achieved. Toh Bhi after some time aisa ho sakta h na...ki fir se sys. And surr. Thermal equilibrium me aa jaye...although... We cant say that very initally P,V,T ki jo values the that may not be same now...but if still with new P',V',T' system is back to equilibrium again.then,would you call it reversible or irreversible ??
Sir irrev process me original state regain kyun nai ho payega wapas block rakho equilibrium pe aa toh jayega na Iski feeling nai aai sir koi example dijiye na ki kaise original state regain nai ho pata Pls answer sir 🙏
Sir in the analogy used for irreversible reaction, if the path followed by the system is reversed i. e. if the weight is added back then the system will regain its original state. Then, how are we classifying it as an irreversible process?
I know my reply is very late, but this is for others who might have the same doubt: (Pasted from wikipedia) A system that undergoes an irreversible process may still be capable of returning to its initial state. Because entropy is a state function, the change in entropy of the system is the same whether the process is reversible or irreversible. **However, the impossibility occurs in restoring the environment to its own initial conditions**. An irreversible process increases the total entropy of the system and its surroundings
#askCompetishun Sir as you have mentioned that when irreversible process is reversed, either system or surrounding or both do not get back to their original state but the example that you have stated above if we will put mass m2 on mass m1 eventually system will get back to it's initial state Can you please explain this point .
Replacing m2 back is a separate process in itself. What he meant was there can never be a spontaneous reversal from the final state back to the initial state.

Lecture 3 completed summary:
Important processes:
Isothermal process:constant tempertaure
Isobaric:constant pressure
Isochoric: volume constant
Cyclic process: just remember it will come back to original state.
And important thing state fucntions are always zero in cyclic process.
Reversible process:a very hypothetical case which will take place very slow in infinite no of small steps.
At every instant in reversible process it is in thermodynamic equilibrium. when the path of reversible is reversed system and surroundings will come back to orginal state unlike irreversible process.
Irreversible process takes place in fintite no of steps.equilibrum will only exist and current and final state of irreversible process

23:18 pr sir if we keep the m2 mass again after final equilibrium is achieved.
Toh Bhi after some time aisa ho sakta h na...ki fir se sys. And surr. Thermal equilibrium me aa jaye...although... We cant say that very initally P,V,T ki jo values the that may not be same now...but if still with new P',V',T' system is back to equilibrium again.then,would you call it reversible or irreversible ??
Actually initially V increased is the path so reverse path is volume decreased in which it is irreverisble
It will be irreversible as during the process of acquiring equibrium there is no equibrium maintained
Sir irrev process me original state regain kyun nai ho payega wapas block rakho equilibrium pe aa toh jayega na
Iski feeling nai aai sir koi example dijiye na ki kaise original state regain nai ho pata
Pls answer sir 🙏
answer mila kya ?

It should be spontaneous
Due to loss of some heat due to friction or any other reasons, final state wont be EXACTLY same as the initial state..

Can you please explain this point .
did you get an answer?
Replacing m2 back is a separate process in itself. What he meant was there can never be a spontaneous reversal from the final state back to the initial state.
sir ye video 11 class wale dekh sakte hai ?
sir please explain in hindi also
yar koi pls batao agar mass m2 dubara rkhoge toh piston phir se niche nhi a jyga toh reversinble process nhi hua?
bhai reversible process me infinite steps lagte hai, jab ki reversible process ginti ke steps me ho jata hai
isliye ye irreversible process hai
Reversible process means at every instant the system and surrounding should be in equilibrium...
❤️❤️❤️
Kisiko last wala point smjh me aaya to pls smjha do kisi example k saath
6:40 Sir, if throughout the process, we give the system 5kJ heat and take 5kJ heat. Then ∆Q=5-5=0kJ but dQ≠0. Is it still considered adiabatic?
i think not? cause by definition there's no heat transfer between system and surrounding. Giving and taking 5kJ energy is considered heat transfer
