Question
a) A heat engine takes 325 kJ of heat from a 1000 K energy reservoir and also 125 kJ of waste heat It throws it into a 400K energy reservoir. Meanwhile, it releases an energy of 200 kJ. Is the cycle in which this heat engine operates reversible? Is it irreversible? Is it impossible? Why? b) An inventor designed a cooling device with an efficiency coefficient of 8.5 between -10°C indoor temperature and 25°C room temperature. He claims to be running his machine. Could this claim be true? Why?
