Answer: from the soup to the ice
Explanation: The heat energy from the soup truly transfers to the ice cube when you put it in a bowl of hot soup. An object with a greater temperature will always transfer heat to an object with a lower temperature. In this instance, the hot soup has a higher temperature than the ice cube due to its higher thermal energy content. The ice cube melts as a result of the heat energy moving from the soup to it, and the soup cools as a result.
