← ScienceWhich outcome occurs when a refrigeration cycle's thermal expansion nears 0 K?
A)Decreased coefficient of performance results✓
B)Compressor motor overheats immediately
C)Refrigerant experiences supercritical behavior
D)System automatically reverses entropy gradient
💡 Explanation
The coefficient of performance decreases at very low temperatures because the decreasing difference between hot and cold reservoirs inhibits heat transfer, due to limitations imposed via the Second Law of Thermodynamics. Therefore, the system's cooling power falls rather than maintaining performance or entering some superconducting state.
