A refrigerator operates between two reservoirs at temperatures of 5°C and 25°C. The refrigerator removes 500 J of heat from the cold reservoir. How much work is required for this process?

In a refrigerator, work is required to transfer heat from a low-temperature reservoir to a high-temperature reservoir. The amount of work required is equal to the heat removed from the cold reservoir. Therefore, the work required is 500 J.
