What is the density of water?

We all went to school and all of us studied physics there, but it was a long time ago and some of the knowledge went nowhere.

A very frequent question related togeneral physics course: what is the density of water? In general, if it is very good to delve into the physics course, it can be recalled that under different conditions the density of water is different.

It is customary to take the density of chemically purified waterat its temperature equal to +4 degrees Celsius. The density of such water is 1 gram per cubic centimeter (1 g / cm), with a change in water temperature in any direction, its density will decrease.
