Halliday, Resnick & Walker — Entropy and the Second Law of Thermodynamics: Problem 22
An insulated Thermos contains 130 g of water at 80.0°C. You put in a 12.0 g ice cube at 0°C to form a system of ice + original water. (a) What is the equilibrium temperature of the system? What are the entropy changes of the water that was originally the ice cube (b) as it melts and (c) as it warms to the equilibrium temperature? (d) What is the entropy change of the original water as it cools to the equilibrium temperature? (e) What is the net entropy change of the ice + original water system as it reaches the equilibrium temperature?
📝 Solution Approach
Given: 130 g, 80.0°C, 12.0 g, 0°C
Find: (a) What is the equilibrium temperature of the system? What are; (b) as it melts and; (c) as it warms to the equilibrium temperature?
