Properties of water: Water is a colorless, odorless, and tasteless liquid at room temperature. It has a high specific heat capacity, meaning it can absorb a lot of heat before it gets hot. Water is a polar molecule, which makes it an excellent solvent. It also has strong cohesive and adhesive properties, leading to surface tension and capillary action. Water's density is highest at 4°C, and it expands upon freezing.
FAQs & Answers
- Why is water called a polar molecule? Water is called a polar molecule because it has a partial positive charge on one side and a partial negative charge on the other, allowing it to dissolve many substances.
- What is meant by water's high specific heat capacity? Water's high specific heat capacity means it can absorb a large amount of heat energy without a significant increase in temperature, which is crucial for regulating climate.
- How does water's surface tension benefit living organisms? Water's surface tension allows small organisms to walk on its surface and enables capillary action, which is essential for water transport in plants.
- What happens to water when it freezes? When water freezes, it expands and becomes less dense than liquid water, which is why ice floats.
