A refrigerator is to maintain eatables kept inside at `9^(@)C`, if room temperature is `36^(@)C`. Calculate the cofficient of performance.

Text Solution

AI Generated Solution

To calculate the coefficient of performance (COP) of a refrigerator, we can use the formula: \[ COP = \frac{T_2}{T_1 - T_2} \] where: - \( T_2 \) is the absolute temperature of the refrigerated space (inside the refrigerator) in Kelvin. ...
