Final answer:
The component in an air conditioning system that converts gas into liquid is the condenser, which helps release heat to the outside environment.
Step-by-step explanation:
In an air conditioning system, the component responsible for converting gas into liquid is the condenser. The condenser functions by removing heat from the refrigerant gas, allowing it to condense into a liquid form.
This process is essential in the refrigeration cycle, as it enables the release of heat collected from the interior of a space, such as a room or vehicle, to be expelled to the outside environment.
The remaining components, namely the compressor, evaporator, and thermostat, serve different purposes in the system. The compressor pressurizes the refrigerant to increase its temperature, the evaporator absorbs heat from the environment to convert liquid refrigerant into gas, and the thermostat regulates the air temperature.
