Water is at a minimum temperature when it is frozen, which is 0 degrees Celsius or 32 degrees Fahrenheit
From my high school memory, I recalled that water has minimum volume when at 4 degrees Celcius. This is why it is able to penetrate rocks as it is cooling and then crack them apart once it freezes again.
Then I found this site http://www.simetric.co.uk/si_water.htm
which states
At 4°C pure water has a density (weight or mass) of about 1 g/cu.cm, 1 g/ml,
1 kg/litre, 1000 kg/cu.m, 1 tonne/cu.m or 62.4 lb/cu.ft
and
When water freezes it expands rapidly adding about 9 % by volume. Fresh water has a maximum density at around 4° Celsius. Water is the only substance where the maximum density does not occur when solidified. As ice is lighter than water, it floats.
Water has its maximum density at 4 degree C.
If you cool or heat water from 4 degree C, the density will decrease.
Minimum density will be at 0 C if you are cooling it from 4 C.
Minimum density will be at 100 C if you are heating it.
Water has its smallest volume (for any given mass) at 4 degrees Celsius.
The density of liquid water is minimal near the boiling point: 0,9584 g/cm3.
Water has the highest density - or smallest volume - at about 4 degrees centigrade.
The maximum volume of a given mass of water is at 3,98 o 0C.

Density of a liquid is indirectly proportional to the temperature. When the temperature raises, the density of the liquid decreases. Therefor the temperature has an effect on water density.
Generally, barring unusual temperatures / pressures the density of water is 1 g / mL The density of water at sea level pressure and 4C temperature is exactly 1 g/mL, at different temperatures it is always less. At different pressures things become more complicated.
No. As long as they're at the same temperature.
Temperature and Salinity
4 degrees Celsius
Water reaches maximum density at 4 degrees Celsius
At 4C density is maximum.It is measured as 1000Kg/m3.
The maximum density of water occurs at a temperature of 4°C
The density of water increase from 100 oC to 4 oC (here is a maximum); after this temperature the density decrease.
expands
In most substances, maximum density occurs at the lowest temperature attainable. The only substance that this is not true for is water, whose maximum density is at 3.98 degrees Celsius.
~4 °C
Its temperature rises. As 40C is the temperature where water has its maximum density, then the density will drop as well
The maximum density of ultrapure water (0,9999720 g/cm3) is at 3,98 0C.
4° C is the temperature of maximum density for water. Change temperature in either direction from there -- whether you warm it or cool it -- the density decreases.
The temperature and salinity of seawater determine its density. Water gets denser as it gets saltier and reaches a maximum density at 4 °C. Salinity does affect the boiling point and freezing point of water, but not its temperature.
