Final answer:
False. The exterior walls of a chest freezer are not used to dissipate heat. The cooling process inside a freezer is achieved through a refrigeration system that removes heat from the freezer's interior.
Step-by-step explanation:
The statement is False. The exterior walls of a chest freezer are not used to dissipate heat to the ambient air. Instead, the purpose of the exterior walls is to provide insulation and prevent the entry of heat from the surrounding environment. The cooling process inside a chest freezer is achieved through the use of a refrigeration system, which involves the compression and expansion of refrigerant to remove heat from the freezer's interior.
In a refrigeration system, a refrigerant is compressed by a compressor, which raises its temperature. The hot refrigerant then flows through condenser coils located outside the freezer, where it releases heat to the surrounding air. This heat transfer process occurs through convection and conduction. The refrigerant then expands in an expansion valve, causing its temperature to drop. This cold refrigerant flows through evaporator coils inside the freezer, where it absorbs heat from the freezer's contents, cooling them down.
Therefore, exterior walls of a chest freezer do not directly dissipate heat to ambient air. It is the refrigeration system that accomplishes the cooling process and removes heat from the freezer's interior by transferring it to the surrounding environment.
