8)A refrigerator absorbs 500 J of heat from a cold reservoir and releases 800 J to a hot reservoir. Assume that the heat-engine statement of the second law of thermodynamics is false, and show how a perfect engine working The Second Law of Thermodynamics 1897 with this refrigerator can violate the refrigerator statement of the second law of thermodynamics
ed to a Carnot refrigerator so that all of the work produced by the engine is used by the refrigerator in extraction of heat from a heat reservoir at 0°C at the rate of 35 kJ-s . The source of energy for the Carnot engine is a heat reservoir 9.7. A Carnot engine is coupl at 250°C. If both devices discard heat to the surroundings at 25°C, how much heat does the engine absorb from its heat-source reservoir? If the...
