일반물리학 1 — Entropy and the Second Law of Thermodynamics: Problem 47
47 A 20 g ice cube at -15°C is placed in a lake whose temperature is 15°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 lake temperature?)
