Which statement describes the condenser's state change?

• A. Low pressure liquid to high pressure liquid
• B. High pressure vapor to high pressure liquid
• C. High pressure liquid to high pressure vapor
• D. Low pressure vapor to high pressure vapor

Answer: (B)

In a condenser, the refrigerant releases heat to its surroundings and changes state from a high‑pressure vapor into a high‑pressure liquid. This heat rejection is what drives the vapor to condense, so the pressure remains high as it becomes liquid. The other transitions don’t describe what a condenser does: it doesn’t turn liquid into vapor, and it’s not a low‑pressure process. This phase change from vapor to liquid at high pressure is what makes the condenser essential in the refrigeration cycle.
