A refrigerator, whose coefficient of performance K is 5, extracts heat from the cooling compartment at the rate of 250 J per cycle. How much heat per cycle is discharged to the room which acts as the high temperature reservoir ?

A refrigerator, whose coefficient of performance K is 5, extracts heat

1.	A refrigerator, whose coefficient of performance K is 5, extracts heat from the cooling compartment at the rate of 250 J per cycle. How much heat per cycle is discharged to the room which acts as the high temperature reservoir ?
Answer» SOLUTION :As ` Q_H= Q_L +W implies " so"Q_H= 250+ 50= 300 J`
