1. Heat transfer to a block of 1.5-kg ice at-10?C melts it to liquid at 10?C in a kitchen. Find the entropy change of the water.

2. In a sink, 5 L of water at 70?C is combined with 1 kg of aluminum pots, 1 kg of flatware (steel), and 1 kg of glass, all put in at 20?C. What is the final uniform temperature and change in stored entropy, neglecting any heat loss and work?

3. A piston/cylinder has constant pressure of 2000 kPa with water at 20?C. It is now heated to 100?C. Find the heat transfer and the entropy change using the steam tables. Repeat the calculation using constant heat capacity and incompressibility.
