There seems to be some confusion here. The polarity of water comes from an skewness in the electric charge distribution of electrons in the water molecule,
which has nothing to do with temperature.
What I think the question refers to is water density.
It just so happens that the maximum density of water is at about 39 degrees Fahrenheit.
This is easy enough to observe. Principally you could just pour up cold water in a measuring glass and heat it up. The volume will then change.
At 4 degrees celsius (about 39 F) water has a density of 999.9720 kg/m^3
while it has a density of 983.2 kg/m^3 at 60 degrees celsius.
At 0 degrees, it has been measured to 999.8395 kg/m^3, so at 4 degrees
it has the highest density of these measurements.
Boil water to change it from liquid to gas. At sea level pure water changes state at 100 degrees Celsius or 212 degrees F.
Since you specify that your question is about water, please remember that water freezes at 0 degrees C or 32 degrees F and is no longer water, but becomes ice.However, because of the mineral content in the water surrounding Antarctica, water can remain liquid down to about 28 degrees F.
When solutes are dissolved in water, many water molecules cluster areound each solute molecule(attracted by polarity) This keeps the solute dispersed in the fluid. The water molecules in these "spheres" are tied up and not free to cross a water permeable membrane.

When water changes from a liquid state (just water) to a solid state (ice) that process is called "freezing." The freezing point of water is 32 degrees Fahrenheit (0 degrees Celsius).
@ 32 degrees F. OR @ 0 degrees C.
32.1 degrees F, or 0.1 degrees C.
Water changes state from a liquid to a gas when heated from 10 degrees Celsius to 80 degrees Celsius.
at 100 Degrees C
Water changes from freezing to boiling at 100 degrees Celsius (212 degrees Fahrenheit).
Yes, 0 degrees Celsius is the freezing point of water. At this temperature, liquid water changes to ice through the process of freezing. The melting point, where ice changes to liquid water, is also at 0 degrees Celsius.
Water changes from liquid to solid state, forming ice, between 0 degrees and 10 degrees Celsius.
Water changes from liquid to solid at 0 degrees Celsius.
32degrees Fahrenheit or zero degrees Celsius
At 0 degrees Celsius, water freezes and turns into ice. This is the temperature at which water changes from a liquid to a solid state.
