A refrigerator is to maintain eatables kept inside at `10^(@)C`. If room temperature is `36^(@)C`, calculate the coefficient of performance.

Text Solution

Verified by Experts

We are given:
`T_(1) = 36^(@)C = (36 + 23) = 309 K`
`T_(2) = 10^(@)C = (10 + 273) = 283 K`
We are to calculate , coefficient of performance , `alpha`
We know that,
Coefficient of performance, `alpha = (T_(2))/(T_(1) - T_(2)) = (283)/(309 - 283) = (283)/(26) = 10.9`.
