Question
An insulated Thermos contains 130 g of water at 80.0C.
You put in a 12.0 g ice cube at 0C 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?
