who refrigerators and freezers
Written by Thalia A refrigerator is a device that keeps food cold. A freezer is a device used to make ice cream, or keep other food cold. Both devices can work with either electricity or gas. They usually have a door that opens and closes and shelves inside to store food. The temperature in them can be set to fit the needs of the person using it. A refrigerator keeps things cool by blowing air into the box, even if there is no power running through it. A freezer compresses the air around an object which causes the object’s temperature to drop below -18 degrees Fahrenheit (-28 Celsius). The inside of it is insulated to protect the food inside. The temperature can be controlled by a dial so people can set it to their liking. It works best if the freezer is half full, so air doesn’t have to circulate as much.
