Final answer:
The cool air from a window air conditioner primarily comes from outside your house. The air is cooled through a refrigerant system that absorbs heat before circulating the cool air back into the room. Thus, the correct answer is that the air started out outside of the house.
Explanation:
The Source of Cool Air from an Air Conditioner
The cool air that blows into your room from a window air conditioner primarily comes from the outside. Therefore, the correct answer is a. started out outside of the house.
Here's how it works: an air conditioner functions by circulating air. It takes in warm air from the inside of a room and passes it over cold refrigerant coils. The refrigerant absorbs the heat from the air, cooling it down.
The cool air is then blown back into your room. Although the air is processed within the air conditioner, it originally started outside before the cooling process. It's important to note that refrigerants like Freon are used in the cooling cycle, but they do not constitute the cool air itself.
Key Functionality of Air Conditioners
- Air conditioners use a refrigerant to absorb heat.
- They extract heat from indoor air to create cooler air.
- They recirculate air, but the source of cool air is outdoor air.
