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.
The maximum density of ultrapure water (0,9999720 g/cm3) is at 3,98 0C.
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.
Density: Mass/volume , so it is obious that density will changed with increase in temperature as volume is proportionaly changes with temperature so density will be decreases with increase in temperature. From this stand point we can say hot water has lower density then the water which is kept in room temperature. In 4'C water has higher density than other temperatures.
Pure water achieves maximum density at 3.98 °C.
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.

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.
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.

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.
The water becomes 100 degrees and is warm to the touch.
