B1 A Carnot device operates berween a cold reservoir of temperature 173 K and a hot reservoir of temperature 503 K.If the device operates as a heat engine, what is its efficiency?If the device operates as a heat pump, what is its coefficient of performance?If the device operates as a refrigerator, what is its coefficient of performance?Which of the statements below most correctly distinguish between a heat engine and a heat pump?OHeat engine operates more efhiciently with a large temperature difference; heat pump operates with higherperformance with a small temperature difference.OHeat engine operates morh efficiently with a large temperature difference: heat pump also operates with higherperformance with a large temperature difference.OThe efficiency of a heat engine and the performance of a heat pump are both independent of temperature differences.What is the best coefficient of performance possible for a hypothetical refrigerator that could make liquid nitrogen at-202.7C and has heat transfer to the environment at 45.8°C ?A Carnot device operates berween the temperatures of 258 K and 493 K. If 6314 J of heat is drawn into the heat engine,how much heat is expelled from the engine?
