Water has five key life-supporting properties: 1) Solvent—it dissolves a wide variety of substances facilitating biochemical reactions; 2) Cohesion and Adhesion—these properties enable water transport in plants and animals; 3) Heat Capacity—water can absorb and release heat with minimal temperature changes; 4) Density—ice floats, providing insulation in aquatic environments; 5) Chemical Reactivity—it participates in essential biochemical reactions like hydrolysis.
FAQs & Answers
- Why is water considered a universal solvent? Water is called a universal solvent because it can dissolve more substances than any other liquid, enabling vital biochemical reactions for life.
- How do cohesion and adhesion support hydration in plants and animals? Cohesion allows water molecules to stick together, and adhesion allows them to cling to other surfaces, helping transport water through plant vessels and animal circulatory systems.
- What is the significance of water's high heat capacity for living organisms? Water's high heat capacity helps regulate temperature in living organisms and environments by absorbing and releasing heat with minimal temperature changes.
- Why does ice float and how does that benefit aquatic life? Ice is less dense than liquid water, so it floats, creating an insulating layer on water surfaces that protects aquatic ecosystems during cold conditions.
