How does freon keep your car cold?
In: 3
It’s something called a “refrigerant”, which means that you can alternate compressing it and evaporating it to move heat from inside the car to outside the car. It’s the same as an air conditioner, a heat pump heater, and refrigerators.
It works because compressing it into a liquid makes one side heat up, while letting it evaporate back into a gas cools it down.
