← ScienceWhich outcome occurs when the ideal Carnot cycle operates in reverse?
A)Heat pump creates cooling effect✓
B)Efficiency reaches theoretical maximum
C)Entropy of system always increases
D)Net work done becomes zero
💡 Explanation
A reversed Carnot cycle implements a heat pump due to the reversed thermodynamic process; rather than producing work, it transfers heat absorbing it from a cold reservoir causing cooling, therefore heat is pumped, rather than a zero work effect.
