Andy holds an ice cube in his hand until the cube melts. By that time, Andy's hand has
become very cold. What is the most complete description of happened?
The thermal energy from Andy's hand flowed in to the ice cube, melting it.
O The cold energy of the ice cube cancelled out with the heat energy of Andy's hand, cooling his hand
and melting the cube.
As the ice cube melted, the water evaporated via sublimation, cooling Andy's hand.
The ice cube's cold energy flowed into Andy's hand, making his hand cold.
