An ice cube of mass 30 g at 0^ C is left sitting on the kitchen table where it gradually melts and reaches the kitchen temperature of 25^0 C . The latent heat of fusion for ice is 333 ~J ~g ⁻¹ and the specific heat of water is 4.2 ~J ~g ⁻¹ ~K ⁻¹ . Select the correct statement(s) about this process. (All numerical values in the answers are rounded to the closest integer.)
Options
- AThe entropy of the kitchen does not change.
- BWhen the ice at 0^ C melts to water at 0^ C its entropy change is 37 ~J ~K ⁻¹ .
- CThe entropy change of the kitchen is -48 ~J ~K ⁻¹ .
- DThe entropy of ice increases.
Correct answer
D. The entropy of ice increases.
