Water's main properties and functions are: 1. High Heat Capacity - Stabilizes temperatures. 2. High Heat of Vaporization - Cools surfaces upon evaporation. 3. Cohesion - Allows water transport in plants. 4. Adhesion - Enables capillary action. 5. Lower Density of Ice - Insulates aquatic environments. 6. Universal Solvent - Dissolves many substances. 7. Transparency - Permits light penetration for photosynthesis. 8. Surface Tension - Supports small organisms. 9. pH Neutrality - Maintains cellular stability. 10. Polarity - Facilitates chemical reactions.
FAQs & Answers
- Why does water have a high heat capacity? Water has a high heat capacity because hydrogen bonds between water molecules absorb and retain heat, which helps stabilize temperatures in the environment.
- How does water's polarity affect its functions? Water's polarity allows it to form hydrogen bonds and dissolve many substances, making it an excellent universal solvent essential for chemical reactions.
- What role does cohesion play in water transport in plants? Cohesion causes water molecules to stick together, enabling the continuous column of water to move upward through plant vessels during transpiration.
- Why is ice less dense than liquid water important for aquatic life? Because ice is less dense, it floats on water and insulates aquatic environments, protecting organisms from freezing temperatures.
