The temperature of Earth's oceans at a depth of \(2500 \mathrm{~m}\) is about \(4{ }^{\circ} \mathrm{C}\). Suppose you want to use this water as the low-temperature thermal reservoir for an electric heat pump to heat the cabin of a boat to \(20^{\circ} \mathrm{C}\). If the pump operates on a Carnot cycle and uses electrical energy at a rate of \(75 \mathrm{~W}\), at what rate are you changing the entropy of the deep ocean and the entropy of the air in the cabin?
