The function of thermostat in the refrigerator is

A thermostat in a refrigerator serves to maintain a consistent internal temperature. It operates by sensing the temperature inside the refrigerator and activating or deactivating the cooling mechanism as needed. When the internal temperature rises above a preset level, the thermostat signals the compressor to start cooling. Conversely, when the temperature drops to the desired level, it turns off the compressor to prevent further cooling. This regulation ensures that the refrigerator maintains an optimal temperature for food preservation, preventing it from becoming too warm, which could spoil the food, or too cold, which could unnecessarily freeze items. By maintaining a steady temperature, the thermostat helps ensure energy efficiency and the effective functioning of the refrigerator. Therefore, the primary function of a thermostat in a refrigerator is to maintain the same temperature, making the correct answer [C] To maintain the same temperature.
