An ideal refrigerator has a freezer at a temperature of \(-13^{\circ} \mathrm{C} .\)The coefficient of performance of the engine is 5. The temperature of the air (to which heat is rejected) will be:
- \(325^{\circ} \mathrm{C}\)
- \(325 K\)
- \(39^{\circ} \mathrm{C}\)
- \(320^{\circ} \mathrm{C}\)
Answer
(C) 39^ C
