How Do Refrigerators Work?

A Refrigerator is a device that keeps food inside of it cool to preserve it. Here is how a Refrigerator works. First, a fluid called Refrigerant is pumped from a container in the back of the Fridge. This Refrigerant gets pumped through the pipes inside of the cooling compartment (where you put the stuff to be cooled). As the Refrigerant goes through the cooling compartment, it absorbs the heat from the food. This is what makes it cold. The Refrigerate turns into a gas and is turned back into a liquid through a compressor. This is how a Refrigerator works.

A Refrigerator preserves food because fungi and bacteria can’t grow as fast when food is cold.
