Question:

A heat pump operates on Carnot cycle pumps heat from a reservoir at 27°C to 327°C. The Coefficient of performance is

Show Hint

For Carnot cycles, the COP can be calculated using the temperatures of the hot and cold reservoirs. Higher temperature differences lead to lower COP values.

The Correct Option is C

Solution and Explanation

The Coefficient of Performance (COP) for a Carnot heat pump is given by: \[ COP = \frac{T_H}{T_H - T_L} \] Where: - \( T_H = 327°C + 273 = 600 \, K \) - \( T_L = 27°C + 273 = 300 \, K \) Substituting these values into the equation: \[ COP = \frac{600}{600 - 300} = 2 \]
