During that second, the engine does 3100 J of work. (a) What is the engine’s efficiency? (b) The burning gasoline has a temperature of about 2500 K. The waste heat from the engine flows into air at about 290 K. What is the Carnot efficiency of a heat engine operating between these two temperatures?Answer QuestionBe the first to answer this question.
