The data listed below are claimed for power cycles operating between hot and cold reservoirs at 1000 K and 400 K, respectively. For each case determine whether such a cycle is in keeping with the first and second laws of thermodynamics. a) Qh=300 kJ, W(cycle)=160kJ, Qc=140 kJb) Qh=300 kJ, W(cycle)=180kJ, Qc=120 kJc) Qh=300 kJ, W(cycle)=170kJ, Qc=140 kJd) Qh=300 kJ, W(cycle)=200kJ, Qc=100 kJ
