How does a refrigerator work?

A thin tube loops back and forth inside and outside of your refrigerator. This tube is connected to a pump, which is powered by an electric motor and carries refrigerant inside the tube. The refrigerant starts out as a liquid. The pump pushes the liquid through a lot of coils inside the freezer area. There the chemical turns to a vapor. So when the gas expands it becomes very cold and the principle of
HOT TRAVELS TO COLD” happens. The coils soak up some of the heat that is inside the freezer thus the refrigerator becomes colder.

The pump then forces the refrigerant through thinner pipes which are on the outside of the refrigerator. By compressing it, the refrigerant now turns back into a liquid. A fan will blow over the coils to help release the heat to the air outside of the refrigerator. Once the refrigerant passes through the outside coils, the liquid is ready to go back through the refrigerator and repeat the process over and over again.

LAWS OF GAS: To put it simple “GAS COOLS ON EXPANSION.”
