What causes frost to form on the inside of refrigerators?
Frost forms on the inside of refrigerators when warm, moist air enters the refrigerator and comes into contact with the cold surfaces inside. The moisture in the air condenses and freezes on these cold surfaces, resulting in frost buildup. This can happen if the refrigerator door is opened frequently, if the door seal is damaged, or if the humidity level inside the refrigerator is too high.
Is a refrigerator an insulator?

How does freon help to keep the temperature in a refrigerator down to freezing temperature?
Freon is the registered name for a number of products containing halocarbons. These refrigerants undergo a process where it condenses into a liquid and evaporates into a solid, losing a substantial amount of heat in the process. Once it's cold enough, the gas is channeled through coils that allow it to absorb heat from the air in the fridge.
