QUESTION 10 The Kelvin-Planck and Clausius statements of thermodynamics are equivalent. In order to prove the equivalence, a heat-engine-refrigerator combined system is used as shown below. The system satisfies the following conditions, where QH and QL are known values 1) Heat recieved by the heat engine from the source: QH,HE=QH 2) Heat QH is completely converted into net work output from the heat engine: QH-Wnet 3) Heat recieved by the regrigerator from the sink: QL,R=QL Select the correct statement for this combined the system.__ HE QH.HE=QH QLHE O TH 'net, HE TL R QH.R QLR=QL O A. The system receives heat QL from the sink and transfer 100% of the heat QL to the source without any work input, which violates the Clausius statement. B. The system receives heat QL from the sink and transfer 100% of the heat QL to the source without any work input, which violates the Kelvin-Planck Statement. C. The system receives heat QL from the sink and transfer QH-QL amount of heat to the source, which does not violate the second law of thermodynamics. D. The system receives heat QH from the sink and transfer 100% of the heat QH to the source without any work input, which violates the Clausius statement.
The Kelvin-Planck and Clausius statements of
1) Heat recieved by the heat engine from the source: QH,HE=QH
2) Heat QH is completely converted into net work output from the heat engine: QH=Wnet
3) Heat recieved by the regrigerator from the sink: QL,R=QL
