Question

An insulated Thermos contains 149 g of water at 71 C. You place in a 10.7 g ice cube at 0 C to form a system of ice + original water.

(a) What is an equilibrium temperature of the system?
What are the entropy changes of water that was initially the ice cube?

(b) As it melts and

(d) What is an entropy change of the new water as it cools to the equilibrium temperature?

(e) What is the net entropy change of the ice + original water system as it reaches equilibrium temperature?
