Show answer and explanation

Correct answer: (A) P: vapour at low pressure; (C) R: liquid at high pressure; (D) S: liquid-vapour mixture at low pressure

Explanation

P is the low-pressure vapour entering the compressor (A). Compression raises pressure, so Q is high-pressure vapour and B is false. Condensation produces high-pressure liquid at R (C); expansion gives a low-pressure two-phase mixture at S (D). Select A, C, D.
