What is the entropy change of ice to water and water to vapor?


1.) What is the entropy change of a 33.0 g ice cube that melts completely in a bucket of water whose temperature is just above the freezing point of water? (J/deg)




2.) What is the entropy change of a 7.3 g spoonful of water that evaporates completely on a hot plate whose temperature is slightly above the boiling point of water?
