Study Notes
Water Composition and Structure
- Water is an inorganic molecule composed of two elements: hydrogen and oxygen.
- The chemical formula for water is H2O, indicating that each water molecule consists of 2 hydrogen atoms linked to 1 oxygen atom.
Importance of Water
- Water is essential for life on Earth, and without access to it, life would not exist on our planet.
Properties of Water
- Water is a polar molecule due to the presence of hydrogen bonds.
- Hydrogen bonds are responsible for water's high heat capacity.
- Water has a high latent heat of vaporization.
- Water expands and becomes less dense when it freezes.
Water Movement and Behavior
- Capillary action is the movement of water through a plant's roots.
- The process of water changing from a liquid to a gas is called evaporation.
- The attraction of water molecules to each other is termed cohesion.
Water Characteristics
- Ice is less dense than liquid water.
- Water is the main component of cells, making up a significant portion of their structure.
