During the power stroke of an internal combustion engine, the air-fuel mixture is ignited and the expanding hot gases push on the piston. Fuel efficiency is maximized in this process when the ignited gas is as hot as possible, the gas expands allowing a maximum amount of work to be done, and cooled exhaust gas is released at the end of the cycle. Assuming the engine exhibits the highest efficiency possible, which of the following statements concerning the exhaust gas...
