    Sourav are you there

    eduncle-logo-app

    yes sir

    eduncle-logo-app

    I hope you know work done in reversible expansion is greater than irreversible expansion

    eduncle-logo-app

    yes sir

    eduncle-logo-app

    I am telling just about magnitude as work done is -ve in expansion

    eduncle-logo-app

    Then you will also accept that expansion leads to cooling

    eduncle-logo-app

    Sourav please ask if you get stuck

    eduncle-logo-app

    im asking why rev temp is less than irr temp

    eduncle-logo-app

    for adiabatic

    eduncle-logo-app

    please answer my question. I am getting to your question

    eduncle-logo-app

    yes sir.. adiabatic exp causes cooling

    eduncle-logo-app

    if more work is done in reversible work then it will cause more cooling.

    eduncle-logo-app

    yes sir, i get your answer what are you trying to say.. i was pretty much cleared about this thing but then i came across one article.. can you check https://www.quora.com/Why-does-temperature-decrease-more-in-adiabatic-irreversible-expansion-than-in-adiabatic-reversible-expansion/answer/Nikhil-Kashyap-32?ch=10&share=155fd5af&srid=8hHwr

    eduncle-logo-app

    you are saying more work more cooling, so rev temp must be less than irr work.. I completely agree.. But then i saw that one

    eduncle-logo-app

    yes Sourav correct

    eduncle-logo-app

    i am looking at it please wait

    eduncle-logo-app

    did you check it sir?

    eduncle-logo-app

    please wait

    eduncle-logo-app

    There is a flaw in it Sourav

    eduncle-logo-app

    Sourav are you there

    eduncle-logo-app

    yes sir.. plz continue

    eduncle-logo-app

    sir you there?

    eduncle-logo-app

    sir i checked it one hr earlier . plz check.. both of the statements contradict... in qs it is said final temp irr is greater while in quora it is saying final temp rev is greater. I am not getting legit answer.

    eduncle-logo-app

    and according to answer key, statement 1 is correct

    eduncle-logo-app

    okk let me check..

    Answer to Why does temperature decrease more in adiabatic irreversible expansion than in adiabatic reversible expansion? by Nikhil Kashyap https://www.quora.com/Why-does-temperature-decrease-more-in-adiabatic-irreversible-expansion-than-in-adiabatic-reversible-expansion/answer/Nikhil-Kashyap-32?ch=99&share=155fd5af&srid=8hHwr

    eduncle-logo-app

    sir check this one

    eduncle-logo-app

    so that's why let me verify this in standard books

    eduncle-logo-app

    ok
