FAA AMT Airframe Test 2026 – 400 Free Practice Questions to Pass the Exam

As the refrigerant travels through the vapor cycle cooling system, it undergoes phase changes from high pressure vapor to low pressure liquid and back to high pressure liquid. This occurs as the refrigerant absorbs heat from the surroundings, evaporates, and then releases that heat as it condenses. Therefore, the condition of the refrigerant as it leaves the condenser would be high pressure liquid, making option D the correct answer. Option A is incorrect because the refrigerant has already evaporated and is no longer in its liquid state after the condenser. Option B is incorrect because the refrigerant would have already been compressed to a high pressure in the compressor stage, and option C is incorrect because the refrigerant has already been condensed and is no longer in its vapor state.
