1.What is the true density of water?
polet [3.4K]

\huge\color{red}{\boxed{\tt{A}}}\color{orange}{\boxed{\tt{N}}}\color{lime}{\boxed{\tt{S}}}\color{aqua}{\boxed{\tt{W}}}\color{violet}{\boxed{\tt{E}}}\color{pink}{\boxed{\tt{R}}}\color{magenta}

  1. A common unit of measurement for water's density is gram per milliliter (1 g/ml) or 1 gram per cubic centimeter (1 g/cm3). Actually, the exact density of water is not really 1 g/ml, but rather a bit less (very, very little less), at 0.9998395 g/ml at 4.0° Celsius (39.2° Fahrenheit).
  2. Water density changes with temperature and salinity. Density is measured as mass (g) per unit of volume (cm³). Water is densest at 3.98°C and is least dense at 0°C (freezing point). Water density changes with temperature and salinity.
  3. When water is a liquid, the water molecules are packed relatively close together but can slide past each other and move around freely (as stated earlier, that makes it a liquid). Pure water has a density of 1.000 g/cm3 at 4˚ C. As the temperature increases or decreases from 4˚ C, the density of water decreases.
