Water is a unique substance with remarkable physical properties. It has a high heat capacity, meaning it can absorb a lot of heat before its temperature rises. It is also a universal solvent, dissolving many substances due to its polar nature. Water exhibits cohesion (water molecules stick to each other) and adhesion (water molecules stick to other surfaces). It has an anomalous expansion; water expands when it freezes, making ice less dense than liquid water, allowing it to float.
FAQs & Answers
- What are the main physical properties of water? The main physical properties of water include high heat capacity, being a universal solvent, cohesion, and adhesion.
- Why does ice float on water? Ice floats on water because it expands when it freezes, making it less dense than liquid water.
- How does water's solvent capability affect living organisms? Water's solvent capability is crucial for biological processes, allowing nutrients and chemicals to dissolve and transport within living organisms.
- What is meant by the term 'anomalous expansion' of water? Anomalous expansion of water refers to the unusual behavior of water expanding upon freezing, which is not common in most substances.
