A refrigerating machine working on a reversed Carnot cycle takes out ...
Given data:
- Heat extracted, Q = 2 kW/min
- Temperature limits: T1 = 300 K, T2 = 200 K

Coefficient of Performance (COP):
- COP of a refrigerating machine working on a reversed Carnot cycle is given by COP = T2 / (T1 - T2)
- Substituting the given values, COP = 200 / (300 - 200) = 200 / 100 = 2

Power consumed by the cycle:
- Power consumed by the cycle can be calculated using the formula: COP = Q / W, where W is the power consumed
- Substituting the given values, 2 = 2 / W
- Therefore, W = 1 kW
Therefore, the correct answer is option C: COP of 2 and power consumed by the cycle of 1 kW.
