Question

A refrigerator is to maintain eatables kept inside at 90C. If room temperature is 360C, calculate the coefficient of performance.​

Answer 1

Solution :-

Given:

Room temperature, T2 = 35°C = 35 + 273 = 308 K

Temperature inside the refrigerator, T1 = 8°C = 281 K

Since, the Coefficient of performance =

$\tt \: \frac{T_1}{T_2 - T_1 } = \frac{281}{308 - 281} = \frac{ \cancel{281}}{ \cancel{27}} = \red{10.41}$

Therefore, the coefficient of performance of refrigerator is 10.41.
