Question
If the coefficient of performance of a refrigerator is 5 and operates at the room temperature 27C, the temperature inside the refrigerator is: A 240 K B 250 K 230 K 260 K
Transcribed Image Text:If the coefficient of performance of a refrigerator is 5 and operates at the room temperature 27C, the temperature inside the refrigerator is: A 240 K B 250 K 230 K 260 K
Expert Solution
Step 1

Given,

Coefficient of performance of refrigerator = COP = 5

Room temperature = TH = 27 oC = 300 K

 

Let us take the temperature inside refrigerator = TL

 

COP of the refrigerator is given by,

    COP = TLTH - TL∴ 5 = TL300 - TL∴ 1500 - 5 TL = TL∴ 6 TL = 1500∴ TL = 250 K
