1. Density: Water is most dense at 4°C and less dense as a solid than a liquid, causing ice to float. 2. High Specific Heat: Water can absorb a lot of heat without a large change in temperature, which helps regulate climate and body temperature. 3. Surface Tension: Water molecules stick together strongly, allowing for droplet formation and certain insects to walk on water.

FAQs & Answers

  1. Why is water density important? Water density affects buoyancy, aquatic life, and the overall structure of ecosystems.
  2. How does high specific heat impact climate? Water's high specific heat helps moderate temperatures, influencing local and global climates.
  3. What role does surface tension play in nature? Surface tension allows some insects to walk on water and is essential for various biological processes.
  4. How are the properties of water related to life? The unique properties of water enable it to sustain life, influencing biological functions and ecosystems.
