Water density: kg/m3

Distilled water has the smallest volume and the largest density at 4°C, which is 1.0g/cm3 or 1000kg/m3. When other substances are dissolved in water, the density of the solution will increase accordingly. The greater the concentration, the greater the density. When the temperature of water is lower than 4°C (greater than 0°C) or greater than 4°C, the density of water will decrease.
