A 12 g ice cube at -13 °C is placed in a lake whose temperature is 19 °C. Calculate the change in the entropy of the cube-lake system as the ice cube comes to thermal equilibrium with the lake. (The temperature of the lake does not change). Hint: You will need to calculate the entropy change of the 12 g of ice/water as well as the entropy change of the lake. These two wills be of opposite sign and fairly close in absolute value. Maintain extra precision in your calculations so that the difference is not off by a large fraction. Your answer should be in J/K, but enter only the numerical part in the box.
