1. Cohesion and Adhesion: These properties allow water to stick to itself and other surfaces, facilitating processes like nutrient transport in plants. 2. High Specific Heat: Water can absorb and retain heat, stabilizing temperatures in environments essential for life. 3. Universal Solvent: Water's ability to dissolve many substances supports biochemical reactions. 4. Ice Density: Ice floats on liquid water, creating an insulating surface layer that protects aquatic life in cold climates.
FAQs & Answers
- Why is cohesion important for water in plants? Cohesion allows water molecules to stick together, enabling efficient transport of water from roots to leaves through plant vessels.
- How does water's high specific heat benefit living organisms? Water's high specific heat helps regulate temperature in organisms and environments, preventing rapid temperature changes that could be harmful.
- Why is water called a universal solvent? Water can dissolve a wide variety of substances, which supports essential biochemical reactions in living organisms.
- What is the significance of ice floating on water? Ice floats because it is less dense than liquid water, forming an insulating layer that protects aquatic life during cold seasons.
