Chapter 20: Problem 27
A refrigerator with a coefficient of performance of 3.80 is used to cool \(2.00 \mathrm{~L}\) of mineral water from room temperature \(\left(25.0^{\circ} \mathrm{C}\right)\) to \(4.00^{\circ} \mathrm{C} .\) If the refrigerator uses \(480 .\) W, how long will it take the water to reach \(4.00^{\circ} \mathrm{C}\) ? Recall that the heat capacity of water is \(4.19 \mathrm{~kJ} /(\mathrm{kg} \mathrm{K})\) and the density of water is \(1.00 \mathrm{~g} / \mathrm{cm}^{3}\). Assume that all other contents of the refrigerator are already at \(4.00^{\circ} \mathrm{C}\).
