← ScienceWhich outcome results when a non-ideal heat engine operates?
A)Entropy increase exceeds heat addition✓
B)Complete heat-into-work conversion occurs
C)Reversible heat transfers are guaranteed
D)Carnot efficiency reaches theoretical limits
💡 Explanation
Due to irreversibilities, entropy generation occurs through frictional and thermal losses; therefore, the increase in entropy surpasses any theoretical minimum related to the heat input, rather than achieving perfectly convertible or reversible operation as in ideal cycles.
