Question
True or False: A nonideal engine operating between the same temperature extremes as a Carnot engine and having the same input thermal energy will perform the same amount of work as the Carnot engine. Explain. (Select all that apply.)-False. Since the Carnot engine has the greatest efficiency possible, other engines operating between the two temperatures produce less useful work output for the same work input.
-False. Carnot engines do not really exist. All real engines are less efficient.
-False. All other engines operating between the two temperatures produce more useful work output than the Carnot engine for the same work input.
-True. The efficiency of any heat engine is determined only by its input and output temperatures.
-True. The Carnot engine is a model that accurately describes all heat engines.
