1 Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v. 2  The density of water is 1 gram per cubic centimeter.  The density of a substance is the same regardless of the size of the sample.
Good question and the answer lies in a very peculiar property of water. As you guessed, the density of water of water increases as the temperature is lowered, but below 4 o C this trend is reversed. Here is a graph from. It shows the density of liquid water vs. temperature.
