Liquid water has a constant density. Do you agree or disagree with this statement? Why or why not?

Density is NOT constant, but for liquids and solids it doesn't change very much with temperature or pressure. Liquids and solids expand only slightly with increasing temperature, and they compress only slightly with increasing pressure, so their densities are approximately constant under most ordinary condition.Using Water as a Density ComparisonWhen an object is placed in water, the object's relative density determines whether it floats or sinks. If the object has a lower density than water, it will float to the top of the water. An object with a higher density will sink. ... Liquids tend to form layers when added to water.

disagree. Temperature increases, water expands.
