Suppose that a certain refrigerator is observed to remove 23 J of heat from its interior, while drawing 12 J of energy from the electric grid and exhausting 35 J of heat to the kitchen in which it sits. If the food inside the refrigerator is maintained at 2.85C and the room temperature of the kitchen stays at 62.85C, then at what fraction of this refrigerator's theoretical maximum possible coefficient of performance is its current operating coefficient of performance?

You place your lunch leftovers in the refrigerator. Suppose the refrigerator needs to remove 9.8700E+3 J of thermal energy from your lunch to cool it to the temperature of the inside of the refrigerator. In the meantime, this means the refrigerator produces 1.3702E+4 J of thermal energy that it expels into the kitchen as a result. What is the total work done by the compressor motor in the refrigerator?(Ignore any thermal loses due to friction in the motor.) 3.832×103 J...

An ice-making machine inside a refrigerator operates in a Carnot cycle. It takes heat from liquid water at 0.0∘C and rejects heat to a room at a temperature of 24.5 ∘C. Suppose that liquid water with a mass of 84.4 kg at 0.0∘C is converted to ice at the same temperature. Take the heat of fusion for water to be Lf = 3.34×105 J/kg . Part A How much heat |QH| is rejected to the room? Express your answer in...
