Question
**Problem Statement:** The motor that drives a refrigerator produces 160 W of useful power. The hot and cold temperatures of the heat reservoirs are 20.0°C and −5.00°C. What is the maximum possible amount of ice it can produce in 2.00 h from water that is initially at 8.00°C? Latent heat of fusion of ice is 333700 J/kg and specific heat capacity of water is 4186 J/(kg·K). **Calculate:** □ kg **Explanations:** In this problem, you are asked to compute the maximum possible amount of ice that a refrigerator can produce from water initially at 8.00°C, within a span of 2 hours, with the given parameters: - Useful motor power: 160 W - Hot reservoir temperature: 20.0°C - Cold reservoir temperature: −5.00°C - Latent heat of fusion of ice: 333700 J/kg - Specific heat capacity of water: 4186 J/(kg·K) The goal is to determine the mass of ice produced using the given data.
