← ScienceWhich risk increases when a Carnot heat engine's cooling system fails?
A)Engine overheating and component failure✓
B)Decreased engine combustion efficiency
C)Elevation in compressor pressure
D)Accelerated fuel detonation sensitivity
💡 Explanation
Reduced heat dissipation from the cold reservoir elevates engine temperature through adiabatic expansion, therefore increasing the risk of overheating and component failure because energy isn't removed during operation; rather than improving or misfiring the working fluid.
