Solve the all parts of given problem:

Problem: In an experiment, 280 g of aluminum (with a specific heat of 900 J/kg • K) at 100°C is mixed with 52.0 g of water (4186 J/kg•K) at 20°C, with the mixture thermally isolated.

Part A: What is the equilibrium temperature?

Part B: What is the entropy change of the aluminum? (Enter your answer to at least three significant figures.)

Part C: What is the entropy change of the water? (Enter your answer to at least three significant figures.)

Part D: What is the entropy change of the aluminum-water system?

Show how you get the answer, so that I can better understand how to do it.
