The wonder of water

The video explains the significance of water, highlighting its role in energy creation, travel, and bodily functions. Water is unique as it naturally exists in three states: liquid, solid, and gas. It is a transparent, colorless liquid that acts as a good solvent, dissolving many substances to form solutions. When cooled to 0°C, water freezes into ice, which is less dense than liquid water, allowing it to float. At 100°C, water boils and turns into steam. Water is the most common substance on Earth and is essential for life.
