Study Notes
Physical Properties of Water
- Water is a polar molecule, leading to hydrogen bonding which contributes to its unique properties.
- High specific heat capacity allows water to absorb and store heat with minimal temperature change.
- Water has a high heat of vaporization, providing a cooling effect (such as sweating) during the phase transition from liquid to gas.
- The density of water decreases as it freezes, making ice less dense than liquid water, allowing it to float.
- Water exhibits cohesion due to hydrogen bonding, which helps in water transport in plants through capillary action.
- Adhesion enables water to interact with different materials, crucial for processes like water's ability to climb surfaces.
- Water has a high solvent capacity, often referred to as the "universal solvent," due to its ability to dissolve a wide array of substances.
- The pH level of pure water is neutral at 7, which is crucial for many biochemical processes.
- Water has a thermal conductivity that helps in heat distribution within ecosystems.
- Surface tension is notably high in water, allowing small objects to rest on its surface and supporting various life forms.
