A 150. gram ice cube at zero degrees Celsius is melted and warmed to 20 degrees Celsius.

What is the change in entropy as a result of these two changes, the change of state and heating process?

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

The total change in entropy is $44.4\text{ J/K}$.

B

The total change in entropy is $184\text{ J/K}$.

C

The total change in entropy is $221\text{ J/K}$.

D

The total change in entropy is $228\text{ J/K}$.
