When refrigerant enters the metering device, what state is it in?

Explanation:
The refrigerant entering the metering device is in a high-pressure liquid state. After the condenser, the refrigerant is condensed into high-pressure liquid, and the metering device then drops that pressure to feed the evaporator. Because of this pressure drop, some of the liquid may flash into vapor, creating a low-pressure, liquid–vapor mixture as it moves into the evaporator. If it were already vapor, the condenser wouldn’t have condensed it; if it were low-pressure liquid, it would have to be before the condenser, which isn’t the entering state for the metering device.
