Which outcome occurs when a flawed seal in a refrigerator Carnot engine degrades?

A)Reduced system coefficient of performance
B)Increased internal component temperatures
C)Motor overcurrent limit cycle triggering
D)Refrigerant phase change equilibrium instability

💡 Explanation

Reduced performance occurs because declining seal integrity reduces the refrigeration **adiabatic expansion**, allowing heat infiltration and reducing the temperature differential. Therefore the Coefficient of Performance drops because less heat is removed, rather than a temperature rise or electrical issue.
