A refrigerant gives up heat during the condensing process. This occurs when the refrigerant, which initially absorbs heat from the environment during evaporation, changes from a gas back into a liquid. In this state, the refrigerant releases the heat it had absorbed, typically through the condenser coil in an air conditioning system.

This phase change is critical in the refrigeration cycle. When the refrigerant moves through the condenser, it loses energy in the form of heat to the outside air or water, allowing it to transition back into a liquid state. This heat exchange is fundamental to the cooling process, as it helps to remove heat from the indoor environment, thereby cooling the space.

Understanding this process is key for anyone working with air conditioning systems, as it highlights the importance of efficient heat exchange mechanisms within the system. The other options, while related to changes in state or behavior of a refrigerant, do not pertain to the specific phase where heat is released into the environment.
