Calculate the change in entropy of the cube-lake system

Reference no: EM13538480

A 78 g ice cube at -18°C is placed in a lake whose temperature is 12°C. Calculate the change in entropy of the cube-lake system as the ice cube comes to thermal equilibrium with the lake. The specific heat of ice is 2220 J/kg·K. (Hint: Will the ice cube affect the temperature of the lake?)
