Difficult# Ice To Water To Steam Entropy

APPH12-9R71TR

A 200 gram cube of ice at 0° Celsius melts to water at 0° Celsius. The water is then heated to 100° Celsius. Finally, the hot water is boiled to produce steam at 100° Celsius.

- $L_{ f }=3.34\times { 10 }^{ 5 }\text{ J/kg }$
- $C =4186\frac { J }{ kg•C° } $.
- $L_{ v }=2.26\times { 10 }^{ 6 }\text{ J/kg}$

What is the best value for the change in entropy that occurs as a result of these two change of states and the heating process?
