"How is the entropy change for the second process calculated?"
Not sure how to calculate ANY entropy process, the textbook I have here (Sears and Zemansky's University Physics) gives me an equation dS = ∫dQ/T, where S is the entropy, Q is the heat energy and T is the absolute temperature, but...
Homework Statement
A 4.50 kg block of ice at 0 C falls into the ocean and melts. The average temperature of the ocean is 3.50 C, including all the deep water. By how much does the melting of this ice change the entropy of the world?
