- 43) The compressor in a refrigerator performs 580 J of work to remove 160 J of heat from the refrigerator. How much heat is discharged into the kitchen? A) 340 J B) 420 J C) 540 J D) 640 J E) 740 J800 J of work are done BY a system in a process that decreases the thermal energy of the system by 50 J. How much heat is transferred TO the system during this process? If the system gains heat, answer with a positive number. If the system loses heat, answer with a negative number. (in J) -750 750 -850 -50 04. Suppose that a nuclear power plant has an efficiency of about 0.34, and generates 1000 MW of power. It is located on the banks of a major river that is 67 m wide near the plant, approximately 3 m deep, and flows at a rate of 0.5 m/s. Suppose that the plant re-routes all of this water into the plant and dumps its waste heat evenly throughout the water, then returns the warmer water to the river. How much warmer is the river downstream of the plant compared to upstream? Water's specific heat is approximately 4184 J/kg/K, and its density is 1000 kg/m³. [Answer: The water is warmer by 4.62 K. This is a lot warmer!]
