A refrigerator has a coefficient of performance of 2.25, runs on an input of 95 W of electrical power, and keeps its inside compartment at 5 degrees celsius. IF you put a dozen 1.0 L plastic bottles of water at 31 degrees celsius in the refrigerator, how long will it take for them to be cooled down to 5 degrees celsius? (ignore any heat that leaves the plastic)
