Solve the all parts of following problem:
Problem: A 51 g piece of ice at 0.0°C is placed in an insulated calorimeter of negligible heat capacity containing 100 g of water at 100°C. 1).
Part A: What is the final temperature of the water once thermal equilibrium is established?
Part B: Find the entropy change of the universe for this process?
I need help to find the entropy change of the universe for this process.
