Lesson: The Carnot CyclePhysics
In this lesson, we will learn how to calculate the efficiency of heat engines and heat pumps from the temperature difference between their reservoirs.
Sample Question Videos
The temperature of a Carnot refrigerator’s cold reservoir is . The hot reservoir has a temperature of . What is the coefficient of performance of the Carnot refrigerator?
A Carnot engine operates between reservoirs at temperatures of K and K. If the engine absorbs J per cycle at the hot reservoir, what is its work output per cycle?
A Carnot engine working between two heat baths of temperatures 600 K and 273 K completes each cycle in 5.00 s. In each cycle, the engine absorbs 10.0 kJ of heat. Find the output power of the engine.
