The six refrigerators are placed in six identical sealed rooms. Rank the refrigerators on the basis of the rate at which they raise the temperature of the room. Rank from largest to smallest. 

P = 400 W
QC.max/At = 1200 J/s
P =250 W
P 1000 W
QC.max/At 1000 J/s
QC.max/At = 3000 J/s
P =750 W
QC.max/At = 1500 J/s
P =500 W
OCmax/At = 1500 J/s
P=500 W
QCmax/At 2000 J/s
