The Nature of Water

The video tutorial explores the unique properties of water, highlighting its ability to exist in three states—solid, liquid, and gas—under normal Earth temperatures. It explains the chemical composition of water as H2O, consisting of one oxygen and two hydrogen atoms. The tutorial also discusses water's role as a solvent, its thermal properties compared to metals, and its elasticity and resistance to compression. These characteristics make water a versatile and essential substance in various applications.
