Cambios físicos: congelamiento y derretimiento

The video explains the properties of ice, describing it as frozen water. It details the freezing process, where water turns into ice below 32°F (0°C), and the melting process, where ice reverts to water when heated. Examples of melting, such as ice cubes and frozen lakes, are provided. The video concludes by categorizing freezing and melting as physical changes.
