The coefficient of performance of a refrigerator is 6.0. The refrigerator's compressor uses 115 W of electric power and is 95% efficient at converting electric power into work. What is the rate at which heat energy is removed from inside the refrigerator?

Answer:

QC=655.5j/s

Explanation:

The performance coefficient  of a refrigerator is defined as the ratio of the heat energy removed from the cold reservoir  to the work  input to the refrigerator:

k=coefficient of performance

QC=heat energy removed from the cold reservoir

W=electric power

k=QC/W

95% OF 115 W =109.25W

6=QC/109.25

QC=655.5j/s

is the rate at which heat energy is removed from inside the refrigerator
