Problem 23E
A sophomore with nothing better to do adds heat to 0.350 kg of ice at 0.0o C until it is all melted. (a) What is the change in entropy of the water? (b) The source of heat is a very massive body at 25.0o C. What is the change in entropy of this body? (c) What is the total change in entropy of the water and the heat source?

ANSWER:Solution 23E
Step 1 of 5:
A sophomore with nothing better to do adds heat to 0.350 kg of ice at 0.0o C until it is all melted. (a) What is the change in entropy of the water?
The ice of 0.350 kg gains entropy by absorbing heat from the sophomore and warms from 0.
Given data,
For ice,
- Temperature,
- Mass of ice, m=0.350 kg
- Latent heat of fusion, L=334
- Specific heat of water, C= 4190 J/kg.K
To find,
Heat gained by ice during melting,
Entropy change in ice during melting,
