The highest theoretical efficiency of a gasoline engine, based on the Carnot cycle, is 0.300 or 30.0%.
(a) If this engine expels its gases into the atmosphere, which has a temperature of 3.05 102 K, what is the temperature in the cylinder immediately after combustion?
K
(b) If the heat engine absorbs 812 J of energy from the hot reservoir during each cycle, how much work can it perform in each cycle?
Weng = J
