THERMO| PATHFINDER| BUILD 30| IRREVERSIBLE ADIABATIC EXPANSION

There is an ambiguity in the problem statement as given in pathfinder. In this Video I have improved the problem statement and provided a lucid explanation. Also many students might be tempted to solve this problem using pressure volume relations for reversible adiabatic process but that would be a conceptual blunder. Hope you like this Video...

One of the very few questions I could solve myself … thank you sir

[jpm]

Sir it is very true for adiabatic equation not valid for irreversible process but it is true during the process we can apply the equation at initial and final state...
In this question it is asking the height when the piston ultimately settle down..
I think we can do with PV^y....

What can we say about the entropy change in following cases
Reversible adiabatic exapansion/ compression
Irreversible adiabatic exp/compression

Since dQ=0 there is tendency to set change in entropy as zero.
How could we analyse the scene here.

Thank you for your amazing content and will definitely share this content to my friends

Sir please bring more no. Of good problems of Pathfinder ...it will be helpful before jee advanced next year 😀

[fighter]

Superb 😎😎
Sir please upload more problems on rotation and fluids also.🙏

[visheshpandeydgps]

Sir why there is irreversible process please explain.

[themadax]

Sir. If qn has stated piston is moving slowly then can we apply pv^y =const?

[nishchalsrivastava]

Op sir plz do bring Mechanics super 5 questions 🙏

[lakshmisuneeta]

Sir, I am aiming for top 100 rank in jee advance. What books did you suggest me sir please?

[mridulrathi]

Sir if i want to send you some problem which is good....where can i do that?

[priyanshb]

sir one doubt im in 10th now what chapters of 11th do i cover in 10th these 4-5 months
