Plz explain 1 option. i can't understand it

yes sir

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

yes sir

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

Then you will also accept that expansion leads to cooling

Sourav please ask if you get stuck

im asking why rev temp is less than irr temp

for adiabatic

please answer my question. I am getting to your question

yes sir.. adiabatic exp causes cooling

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

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

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

yes Sourav correct

i am looking at it please wait

did you check it sir?

please wait

There is a flaw in it Sourav

Sourav are you there

yes sir.. plz continue

sir you there?

im mot able to understand the solution of option one sir

can you explain no 1 option?

check it

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.

and according to answer key, statement 1 is correct

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

sir check this one

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

ok
