(a) A one-ton Carnot refrigerator maintains a cold space at a temperature of \(-15^{\circ} \mathrm{C}\), while the surroundings are at \(40^{\circ} \mathrm{C}\). Determine the power consumption of the refrigerator.

(b) If the same refrigerator is used as a freezer maintaining a temperature of \(-25^{\circ} \mathrm{C}\), while the surroundings maintain at \(40^{\circ} \mathrm{C}\), how much refrigeration will it produce? Assume the same power consumption as calculated in part (a).
