How does the second law relate to heat engines?
Step 1 of 3
Solution 22RQ The second law of thermodynamics states that: it is impossible to extract heat from a hot reservoir and completely convert it to work without exhausting any amount of heat to the cold reservoir. A heat engine actually generates work from heat. So the second law of thermodynamics directly puts constraints on how much heat can be converted to the work. Using the second law of thermodynamics we can actually calculate the efficiency of a heat engine and we can figure out the ways to increase the efficiency of the engine. This is the way, the second law related to the heat engine.
