1. High Heat Capacity: Water absorbs and retains heat, helping to regulate temperature. 2. Cohesion and Adhesion: Water molecules stick to each other and other surfaces, aiding in transportation in plants. 3. Universal Solvent: Water dissolves many substances, facilitating chemical reactions. 4. Ice Density: Ice is less dense than liquid water, allowing it to float and insulate aquatic life.
FAQs & Answers
- Why does water have a high heat capacity? Water's high heat capacity allows it to absorb and retain large amounts of heat, helping to regulate temperature in the environment and living organisms.
- What causes water molecules to stick together? Water molecules stick together due to cohesion, which is a result of hydrogen bonding between molecules, aiding processes like water transport in plants.
- Why is water called the universal solvent? Water is called the universal solvent because it can dissolve many different substances, enabling vital chemical reactions in nature and living organisms.
- How does ice density affect aquatic life? Ice is less dense than liquid water, so it floats and creates an insulating layer on bodies of water that helps protect aquatic life during cold temperatures.
