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.
Yes it contract and the expansion from 4 to 0 degrees is due to the crystallisation of water molecules.
An increase in temperature causes thermal expansion which increases the volume. This cause a decrease in density. Except in the case of water between 0 and 4 degrees C, where increased temperature results in a contraction and so increased density.
32 Degrees Fahrenheit 0 Degrees Celsius
Water freezes at 32 degrees Fahrenheit and 0 degrees Centigrade
0 degrees Celsius is a colder temperature than 40 degrees Celsius. 0 degrees Celsius is the freezing level for water. Any positive number above 0 degrees Celsius is a warmer temperature.

No. When water is cooled it contracts up to 4 degrees Celsius and then it begins to expand till 0 degrees Celsius. This is called the anomalous expansion of water.
no. The density changes
the density of water is mostly high when its at 4 degrees celsius so the answer would be that the density of the water decreases from 4 degrees celsius to 0 degrees celcius

Density of ice at 0 degrees Celsius is 916.8 grams per cubic centimeter or milliliter. The density of fresh water is dependant on the temperature: At 3.98 degrees Celsius the density is 0.999975 grams per milliliter. At 100 degrees Celsius the density is 0.958.35 grams per milliliter.
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.
Density of ice=0.9167 g/cm cubed Density of water=1.0 g/cm cubed
Ice melts at 0 degrees Celsius. That is a speciality of water. At 3.98 degrees Celsius, the density of water is highest before it begins to form ice crystals. Water at this temperature may be a slush of water and ice.
this is known as liquifaction if the gas is cooled to liquid.
