Like most substances water generally become more dense when it is cooled because the molecules are slowing down and they are able to get closer to one another.
However unlike most things liquid water expands when it freezes into a solid. This is because the water molecules, when they are in the form of ice, arrange themselves in a spacious rigid framework in which they are relatively far apart from one another.
However even before the react 0 ⁰C they begin to loosely arrange themselves into the rigid ice framework. This process involves forming bonds with one another. While they do not totally freeze in place until they reach 0 ⁰C they do, on average, end up getting farther apart from one another as they approach 0 ⁰C. It is at the temperature of 4 ⁰C that their tendency to get closer because they are slowing down equals there tendency to get further apart because they are bonding. The density of water will be a maximum at the temperature at they are the closest.
So again, at say 6 ⁰C they are getting closer because the are only slowing down, at 2 ⁰C they are getting farther apart because they are bonding strongly, and at 4 ⁰C the two tendencies exactly cancel each other out.

Water is most dense at what degree celsius?
Water has the greatest density at 4ºC or 39.2ºF
Why density of water maximumof 4degreecelius?
The density of water is a maximum of 4 degrees Celsius because of the open hexagon lattice structures.
At what temperature does maximum density occur?
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.
What is the density of water at 39.6 degree Celsius?
0.9923710 g/mL @39.6C
What is the density of di water at 22.9 degree Celsius?
it is 0.997561, internationally excepted value
What degree Celsius does water reach maximum density?
Water reaches maximum density at 4 degrees Celsius
What changes do happen to water structure at 4 degree celsius?
That's the point of maximum density.
Is water vapor the most dense form of water?
i have read water has maximum density at temprature of 4 degree celsius...so water vapour is not most dense form of water.
Why does water expands at 4 degree celsius?
Water has curious thermal properties. It contracts (gets denser) as it cools down just like other materials. However, at 4 degrees Celsius, it reaches the maximum density of 1 and then starts expanding if it is further cooled. Ice formed at zero degree Celsius is actually less dense than water and floats on it.
What is density of water at 36 degree celsius?
The density of water at 36 0C is 0,99367 g/cm3.
Water is most dense at what Celsius?
The maximum density for water occurs at 4 C.
What temperature does pure water reach maximum density?
4 degrees Celsius
What is the maximum freezing point obtainable?
the maximum freezing point of water is -18 degree Celsius, though others may consider that the maximum freezing point is 0 degree Celsius, the 2 answer are being considered correctly, however the maximum boiling point of water is really 100 degree Celsius and that is the only answer in a boiling point
