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?

A

The change in entropy is $1210\text{ J/K} $.

B

The change in entropy is $1460\text{ J/K} $.

C

The change in entropy is $1710\text{ J/K} $.

D

The change in entropy is $1860\text{ J/K} $.
