← ScienceWhich outcome occurs when an internal combustion engine's cooling system fails completely?
A)Rapid engine overheating and component seizure✓
B)Increased fuel efficiency, reduced exhaust emissions
C)Delayed oil degradation, extended engine lifespan
D)Decreased cylinder pressure, lower peak torque
💡 Explanation
Complete cooling system failure results in rapid engine overheating because the **loss of heat transfer mechanism** allows frictional heat to accumulate rapidly, causing thermal expansion and component seizure; therefore, catastrophic engine failure occurs rather than efficiency gains under normal operating conditions.
