What is the coefficient of performance of this mini-fridge

Reference no: EM13275874

A mini-fridge needs to maintain a temperature of 277 K. The air outside the mini-fridge has a temperature of 301 K. Every fifteen minutes, 2 × 105 J of energy is transferred out of the mini-fridge and 2.5 × 105 J of energy is transferred into the surrounding air.

1) What is the power output (that is, the work done per second) of the compressor in the mini-fridge?

2) What is the coefficient of performance of this mini-fridge?

3) If this mini-fridge were instead cooled by a Carnot engine used as a refrigerator, what would its coefficient of performance be?

4) If the mini-fridge were cooled by a Carnot engine, how much energy would be transferred out of the mini-fridge every fifteen minutes if the power output of the compressor was the same as above?
