Calculate the coefficient of performance of refrigerator working between the temperatures `0^(@)C and 30^(@)C.`

Explanation

To calculate the coefficient of performance (COP) of a refrigerator working between two temperatures, we can use the formula:

\[ COP = \frac{T_L}{T_H - T_L} \]

where:
- \( T_L \) is the absolute temperature of the low temperature reservoir (in Kelvin),
