← ScienceWithin a Carnot heat engine, which consequence results from non-isentropic compression?
A)Reduced thermal efficiency output✓
B)Increased total heat rejection
C)Minimized system entropy production
D)Maintained ideal cycle reversibility
💡 Explanation
Non-isentropic compression generates heat; therefore, less heat converts to work during the Carnot cycle because internal energy and entropy increase during irreversible changes, rather than maintaining the original efficiency under assumed ideal conditions.
