Which of these processes is involved in slowing down the air inside the subsonic diffuser? Correct Answer Adiabatic expansion

The process of slowing down the incoming flow inside the diffuser is done using adiabatic expansion. The pressure is constant throughout, if this was not the case then reduced total pressure in front of the compressor would yield less flow velocity.

Statement (I) : When a bluff body moves at supersonic speed in still air, an attached shock wave is produced at its nose causing the flow to be subsonic behind the shock plane. Statement (II) : A normal shock always transforms supersonic flow into subsonic flow causing increase in pressure, temperature and entropy.
