Afirebox is at 650 k, and the ambient temperature is 250 k. the efficiency of a carnot engine doing 146 j of work as it transports energy between these constant-temperature baths is 61.5%. the carnot engine must take in energy 146 j/0.62 = 237.3 j from the hot reservoir and must put out 91.3 j of energy by heat into the environment. to follow carnot's reasoning, suppose some other heat engine s could have efficiency 70.0%.(a) find the energy input and exhaust energy output of engine s as it does 146 j of work
