1. High Specific Heat Capacity: Water can absorb a lot of heat without a significant rise in temperature. 2. Cohesion and Adhesion: Water molecules stick to each other (cohesion) and to other surfaces (adhesion). 3. Universal Solvent: Water can dissolve many substances, making it essential for biochemical reactions. 4. Density Anomaly: Ice is less dense than liquid water, allowing it to float. 5. High Surface Tension: Water has a strong surface layer that allows small objects to float.
FAQs & Answers
- Why is water’s high specific heat capacity important? Water’s high specific heat capacity helps regulate temperature in environments and organisms by absorbing and releasing heat slowly.
- What causes water to have high surface tension? Water’s high surface tension results from strong hydrogen bonding between water molecules at the surface, allowing small objects to float.
- How does the density anomaly of water affect aquatic life? Because ice is less dense than liquid water and floats, it insulates aquatic life below during cold periods, maintaining stable habitats.
