Water And What It Does (1962)
The film explores the essential role of water in supporting life and its various states—liquid, vapor, and solid. It explains the molecular structure of water and how molecules interact during processes like dissolving, evaporation, and condensation. The film illustrates how temperature affects these processes, demonstrating that heat speeds up dissolution and evaporation, while cold can lead to condensation. It also discusses the expansion of water when it freezes and when it turns into steam, highlighting the practical uses of steam power.
