Problem 2 The highest theoretical efficiency of a gasoline engine, based on the Carnot cycle, is 30%. If this engine expels its gases into the atmosphere, which has temperature of 300K, (a) what is the temperature in the cylinder immediately after combustion? ● ● (b) If the heat engine absorbs 837J of heat from the hot reservoir during each cycle, how much work can it perform in each cycle?
