Irreversibility is related to entropy, we can see the above-mentioned processes follow a curve in a T-s diagram and hence they are irreversible.

I read in Khurmi Book, he mentioned that all process is reversible other then polytropic, polytropic is an irreversible process.
As per Khurmi Answer is FALSE.
As per Khurmi Answer is FALSE.
