Does the refrigerant change state in the compressor?

Explanation:
In this cycle, the compressor handles refrigerant that is already in vapor form. Its job is to compress that vapor, which raises its pressure and temperature so it can later release heat in the condenser. There is no phase change (no liquid forming from gas or gas boiling into liquid) inside the compressor. The refrigerant changes state in the evaporator (liquid to vapor as it absorbs heat) and in the condenser (vapor to liquid as it releases heat). So the correct answer is that the refrigerant does not change state in the compressor.
