please answer the following As a gasoline engine is running, an amount of gasoline containing 12,000 J of chemical potential energy is burned in 1 s. During that second, the engine does 4,000 J of work. What is the engine's efficiency (in percent)? The burning gasoline has a temperature of about 4,300°F (2,600 K). The waste heat from the engine flows into air at about 88°F (304 K). What is the Carnot efficiency (in percent) of a heat engine operating between these two temperatures?
