Answer 1

Answer #1

False

Entropy change of adiabatic reversible process then only entropy change is zero because there will not be any entropy generation in the process

If it is adiabatic irreversible process then there will be entropy generation in this process. It contributes to the entropy change so entropy change is positive for adiabatic irreversible process
