1. State: Water exists in three states of matter: solid (ice), liquid (water), and gas (water vapor).
2. Color: Pure water is colorless.
3. Odor: Pure water is odorless.
4. Density: Water has a density of 1 gram per cubic centimeter (g/cm³) at 4°C. This makes it denser than most liquids at room temperature.
5. Freezing Point: Water freezes at 0°C (32°F).
6. Boiling Point: Water boils at 100°C (212°F) at standard atmospheric pressure.
7. Viscosity: Water has a relatively low viscosity, meaning it flows easily.
8. Surface Tension: Water has a high surface tension due to the strong hydrogen bonds between its molecules. This is why water forms droplets and why some insects can walk on water.
