What is the state of the refrigerant as it enters the condenser?

The refrigerant enters the condenser in a gaseous state. This is because the refrigerant has absorbed heat from the indoor environment in the evaporator and has transitioned into a low-pressure vapor. The role of the condenser is to remove this heat from the refrigerant, allowing it to change from a gas into a liquid. As the refrigerant moves through the condenser, it releases the heat it has absorbed, facilitating the phase change necessary for effective cooling in the system. Therefore, recognizing that the refrigerant is a gas as it enters the condenser is crucial to understanding the refrigeration cycle and how energy transfer occurs within the system.
