Structure and Properties of Water
Why is the structure of water important?
The polar structure of water and its ability to form hydrogen bonds are responsible for many of water’s unique properties.
Why is water a liquid at room temperature?
Because of hydrogen bonding, water molecules are attracted to each other. This attraction requires more energy to break than the average kinetic energy of water molecules at room temperature, so water remains a liquid.
Why does water have a high boiling point?
The strong hydrogen bonds between water molecules require a lot of energy to break to transition from liquid to gas, resulting in a high boiling point (100°C).
Why does water have a high specific heat?
It takes a lot of energy to raise the temperature of water because the energy goes into breaking hydrogen bonds between water molecules, not just increasing their motion. This high specific heat capacity helps regulate Earth’s temperature.
Why does ice float in water?
When water freezes, the hydrogen bonds form a rigid, open structure (ice lattice) that is less dense than liquid water. This is why ice floats!
Why is water a universal solvent?
Water’s polar nature allows it to dissolve many ionic and polar covalent compounds. The positive and negative ends of the water molecule can attract ions and polar molecules, breaking them apart and surrounding them in solution.
Structure and Properties of Water
Water is a valuable natural resource. Water is essential for the survival of all living things. We can’t imagine a world without water. Water is required by animals and plants to complete their daily metabolic activities. Water is required by plants to synthesize their food through the photosynthesis process. We can all go days without food but cannot imagine going days without water; without water, even plants dry out and shed their leaves.
