A claim states that a heat pump has been invented that requires work to be done on the system of 400kJ and delivers energy to its surrounding by heat transfer of 300kJ. Such device is possible O True O False

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 What is the thermal efficiency of the heat engine?__________     A. Wnet/QH=QH/QH=100%   B. QL/QH   C. QH/QL   D. (QH-QL)/QH

3.3 Would it be possible to use a normal domestic refrigerator as a heat source for a small hot tub or whirlpool? If so, what would you estimate to be the maximum heating rate and temperature that a 300 gal whirlpool could reach using a refrigerator that is sized to use a 1 hp electric compressor designed with an evaporator temperature of 10 ° F and condensing temperature of 125 ° F?

A claim states that a power cycle has been invented that produces work of 400KJ and requires energy transfer to the system of 300kJ. Such device is possible. O True O False
