Water has several key properties: it is a universal solvent, highly cohesive and adhesive, and has a high specific heat. It also exists in three states (solid, liquid, gas) under normal Earth temperatures. Its density makes ice float on liquid water, and it plays a crucial role in chemical reactions and temperature regulation in organisms.
FAQs & Answers
- What does it mean that water is a universal solvent? Water is called a universal solvent because it can dissolve more substances than any other liquid, which is essential for chemical reactions and nutrient transport in living organisms.
- Why does ice float on liquid water? Ice floats on liquid water because its solid form is less dense due to the molecular structure of water when frozen, which causes it to expand and become lighter than liquid water.
- What are the three states of water found on Earth? Water exists naturally on Earth in three states: solid (ice), liquid (water), and gas (water vapor).
- How does water’s high specific heat benefit organisms? Water’s high specific heat means it can absorb and retain heat well, helping to regulate temperature in the environment and within living organisms.
