← ScienceWhich outcome limits power extracted from a Carnot engine?
A)Isothermal expansion volume ratio.
B)Adiabatic compression temperature change.
C)Working fluid heat capacity.
D)Irreversible entropy increases.✓
💡 Explanation
Engine power is limited when irreversible entropy generation occurs because mechanical energy is lost as waste heat; therefore, less power is available to be extracted, rather than the volume or fluid capacity being relevant under ideal reversible conditions.
