And sorry guys I don't have the answer as this is from embibe and it doesn't provide the answers
Take two points on an isotherm.
Or another path could consist of a reversible isobaric process and isochoric process.
Isnt the second example above also reversible path?
No @Arush_Sharma is correct only 1 path exists but we can break it into whichever way we want
You seem to sound right but that's what I learnt. (imo we can't choose the type of reversible process?)
and i don't know if the second one is reversible or not, but in that case the answer should be 3.2R no? which is not an option?
Yeah here in formula we break into small carnot cycles
Why we can not remeber the future...answer lies the real understanding of ENTROPY...so read between lines...
