Which appliance is used to keep food cold?

The correct answer is the fridge, which is designed specifically to keep food at a low temperature, inhibiting the growth of bacteria and prolonging the freshness of perishable items. A refrigerator maintains a temperature range that is generally above freezing but below room temperature, making it ideal for storing fruits, vegetables, dairy products, and leftovers.

The freezer, while also a cooling appliance, is used primarily for long-term storage of food at sub-zero temperatures, effectively freezing items for preservation. The stove and microwave serve entirely different functions – the stove is intended for cooking and heating food, while the microwave is used for reheating and cooking food using microwave radiation. These appliances do not serve the purpose of keeping food cold. Understanding the specific role of a refrigerator in food preservation helps clarify its importance in food safety and quality.
