### Understanding a Freezer's Energy UsageA freezer has a coefficient of performance (COP) of 6.30. It is advertised as using 495 kW-h annually. Note that one kilowatt-hour (kW-h) is the amount of energy equal to operating a 1-kW appliance for one hour.#### Calculations and Questions:**(a) On average, how much energy does the freezer use in a single day?**![Incorrect Answer]*Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully.***Explanation:**To find the daily energy usage:- Annual energy consumption = 495 kWh/year- Number of days in a year = 365 days\[ \text{Daily energy consumption} = \frac{495 \text{ kWh}}{365 \text{ days}} \]**(b) On average, how much thermal energy is removed from the freezer each day?**![Incorrect Answer]*Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully.***Explanation:**Given the coefficient of performance (COP):\[ \text{COP} = \frac{\text{Thermal energy removed}}{\text{Electrical energy input}} \]\[ \text{Thermal energy removed} = \text{COP} \times \text{Daily energy consumption} \]**(c) What maximum amount of water at 21.0°C could the freezer freeze in a single day?**- **Given Data:** - Latent heat of fusion of water: \(3.33 \times 10^5 \) J/kg - Specific heat of water: 4186 J/(kg·K)\[ \text{Thermal energy required: Q} = \text{Latent heat of fusion} \times \text{mass of water} + \text{specific heat} \times \text{mass of water} \times \text{temperature change} \]**Explanation:**Use the thermal energy removed calculated in part (b) to determine the mass of water that can be frozen.### ConclusionThe above calculations involve step-by-step understanding of energy usage and thermal dynamics, reflecting practical application of physical principles for a freezer’s operation. If basic concepts and problem solving are applied correctly, accurate results are attainable.
