Refrigerators work by using a refrigeration cycle that involves compressing and expanding a refrigerant gas to absorb and release heat. The refrigerant gas is pumped through coils inside the refrigerator, where it absorbs heat from the interior and releases it outside. This process keeps the inside of the refrigerator cool, preserving food and drinks.

What do you hold cold drinks in that keep them cool?
A cooler, insulated tumbler, or ice bucket can keep drinks cold for a longer period of time.
Why does thermos keep hot drinks hot and cold drinks cold?
A thermos keeps hot drinks hot and cold drinks cold by using a vacuum layer between two walls of the container. This vacuum layer prevents heat transfer by conduction, convection, and radiation. The result is that hot drinks stay hot because heat loss is minimized, and cold drinks stay cold because heat gain is minimized.
Do metal keep drinks cold?
Yes, metal can help keep drinks cold because it has good thermal conductivity which allows it to absorb and transfer heat quickly. This means that a metal can or container will help to maintain the cold temperature of the drink for a longer period of time compared to other materials.
Does Styrofoam cups keep hot drinks hot or cold drinks cold?
A Styrofoam cup will do both. The Styrofoam is an insulator, and, as such, it slows the transfer of heat between the system (the drink) and the surroundings (everything outside the cup) If it is a cold drink, heat moves very slowly through the cup toward the drink. If it is a hot drink, heat moves very slowly through the cup toward the surrounding air.
How do copper cups keep drinks cold?
They don't. It feels colder in your hand and on your tongue because it is the cold escaping the vessel at a faster rate than if it were a more insular vessel. The drink itself feels colder because the mixture is hydrophillic (wants to dissolve in water) and creates an endothermic reaction (absorbs the heat from around it).
