Does changing the mass or volume of water change its density?

Question

Whoever gives me the best answer first I'll give him or her ten points!

Please help!

Answer 1

No.

Water does not compress. Therefore, the density remains constant.

Whether you heat it or cool it, the density does not change.

It remains at a constant density until it reaches the boiling point (where it turns to water vapor) or the freezing point ( where it turns to ice)

Answer 2

No, water is incompressable.

Answer 3

Density is defined as the mass per unit volume, so if you were to pour 1l of water into one bucket and 2l into another, they would both have the same density - the 1l bucket has half the volume of water, but will also have half the mass of 2l of water.

The only way to change the density would be to somehow change the mass of water in a specific volume either by squashing more in (very difficult!) or by changing the temperature.

Answer 4

Density is the one thing that stays constant when you increase the amount of water.

It is measured in grams per liter.

Answer 5

My answer is no. But I think water density can be also changed by sonic [shock] waves. Sound can only propagate through compressable  medium. [I'm sorry for my english].

The density of pure water is a constant at a particular temperature, and does not depend on the size of the sample. That is, it is an intensive property. The density of water varies with temperature and impurities.
