At this temperature, the density of water begins to decrease due to the anomalous expansion of water. Thus, the density of water is highest at 4 degrees C, when it is exactly 1 gram per centimeter cubed. This means water is heaviest at this temperature. Ice floats on water because the density of ice is less than the density of water.

en.wikipedia.org/wiki/Relative_density

Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. The term "relative density" is often preferred in scientific usage.

Water is the only substance on Earth that exists in all three physical states of matter: solid, liquid and gas. When water freezes it expands rapidly adding about 9 % by volume. Fresh water has a maximum density at around 4° Celsius. Water is the only substance where the maximum density does not occur when solidified.

Water never has an absolute density because its density varies with temperature. Water has its maximum density of 1g/cm 3 at 4 degrees Celsius. When the temperature changes from either greater or less than 4 degrees, the density will become less then 1 g/cm 3. Water has the maximum density of 1 g/cm 3 only when it is pure water. Other factors ...

The density of water is the weight of the water per its unit volume, which depends on the temperature of the water. The usual value used in calculations is 1 gram per milliliter (1 g/ml) or 1 gram per cubic centimeter (1 g/cm 3).). While you can round the density to 1 gram per milliliter, there are more precise values for you to use.

Specific gravity is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume Being a ratio of densities...

Dew is small drops of water that are condensed when a high density of water vapor meets a cool surface. Dew usually forms in the morning when the temperature is the lowest, just before sunrise and when the temperature of the earth's surface starts to increase. Condensed water in the air may also refract sunlight to produce rainbows.

In English units, the density of water is 1.936 slugs per cubic foot. A slug is different from a pound because the slug measures the mass of a unit, but a pound measures the force of the unit in relation to gravity.

SG = Specific Gravity of the substance. ρ substance = density of the fluid or substance [kg/m 3] ρ reference = density of the reference [kg/m 3] It is most common to use the density of water at 4 o C (39 o F) as a reference since water at this point has its highest density of 1000 kg/m 3 or 1.940 sl/ft 3. However, also the density at 60 °F ...
