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

∙ 13y agoIts density decreases i.e., it expands.
Water has maximum density at 4 degrees celsius. On further increasing the temperature or decreasing the temperature its density decreases. On heating due to thermal energy molecules vibrate more so volume increases and density decreases. On cooling density decrease is due change in arrangement of molecules with respect to each other. Molecules form hexagonal arrangement which takes more volume .

either direction from there -- whether you warm it or cool it -- the density decreases.

What is the normal freezing point of heavy water?

If an iceberg is made of water and its solid and if its in water and its liquid how does the iceberg float?
Water is unusual in that as it freezes it expands, thus water's density is less when a solid than as a liquid, interestingly water is most dense around 4C.
Does density change if some of the liquid evaporates between the time the liquid is delivered to the beaker and to the time it was measured?
Whether or not the density changes if some of the liquid evaporates between the time the liquid is delivered to the beaker and the time it is measured depends on the liquid. For almost all liquids, the answer is no because there was not enough time. Water will have a density of approximately 1 and if a small amount evaporates, it will still have the same density. If you had the beaker at 100C and the room at 0C and waited until the water was 4C, it would make a difference. If the water was at 40C and the room was at 30C, it would almost make no difference. A very few substances would undergo tremendous cooling. That would bring a corresponding increase in density.
Do all liquids contract as they cool?
I can't speak for ALL liquids but in general probably yes. However, water in particular has what is known as an anomalous expansion, as follows. When you cool water from, let's say 40C it contracts as it gets cooler until about 4C when it starts to expand again. Then at 0C it freezes. So the coldest water is at the top (at this temperature range) because the coldest water is lightest.
Does water contract when cold?
No, it expands- this is because when the particles in the water are heated they move around and cause the water to expand. When water is cooled it contracts. This is because the particles in the water and coming together. When water is cooled it usually becomes ice or expands a little. The volume of ice is 4x greater than water, therefore it actually expands, rather than contracting.

When the water?
When it is as cold as possible before freezing into ice, this will depend on the atmospheric pressure but generally between 0c and 4c
When the water is?
When it is as cold as possible before freezing into ice, this will depend on the atmospheric pressure but generally between 0c and 4c
Explain what happens to volume as water temperature goes from 4C to 0C and freezes.?
This is because at the temperature of 0degree ice is there and ice consists of vacant spaces present in them when we increase the temperature the ice starts melting and gets converted into water and the water compounds occupy the space and therefore the volume decreases as all of the vacant spaces got covered by the water compounds.
The Temperature at which water possesses maximum density is?
At 4C density is maximum.It is measured as 1000Kg/m3.
What happens to the internal energy of an ideal gas when it is heated from 0C to 4C?
it increases
What happens to a sample water when it is heated between 4c and 100c?
Its temperature rises. As 40C is the temperature where water has its maximum density, then the density will drop as well
What does water do when it gets heated?
It depends on the starting temperature of the water and the amount of thermal energy added. Starting from ice (solid water( the changes are:From initial temperature to 0C the ice absorbs heat and its molecules begin to vibrate more quickly.At 0C the ice becomes a liquid. If no further heat is added or lost the ice and liquid water will exist. There is also a water vapour present so that this is called the Triple Point of WaterAbove 0C to about 4C the density of the liquid water increases until maximum e=desity of 1 g/ml is reachedAbove 4C the density starts to decrease as the molecular motion becomes more pronounced. The vapour pressure of the water vapor above the fluid starts to increase.At 100C the vapour pressure is equivalent to atmospheric pressure and the water starts to boilAbove the boiling point the water is converted to steam which exhibits at higher pressures until the Critical point is reached.When water and steam reach 221.2 bar and a temperature of 374.15C), the vapor and liquid are indistinguishable.
Is nickel more dense than water?
Yes. Nickel has a density of 8.912 gm/cm^3, while by definition the density of water (at 4C) is 1.0 gm/cm^3.
When water is placed in a freezer it became ice what does it change?
When Water(Liquid State) is cooled,the energy of molecules of water is absorbed by freezer and their movement is slowed down and they form a structure ICE(Solid State). Though density of ICE should have been greater than water since molecules are coming close due to loss of energy,But it is not the case,Water shows anomalous behavior below 4C where the density starts to decrease with temp and hence ice floats on Water.
What two properties must you know to determin density?
Density is a measure of mass to volume. The density of water at 4C is 1 g/ml. So to determine density of a substance you need to know the mass and the volume. Any density higher than 1 will sink in water and any density lower than 1 will float.
If an iceberg is made of water and its solid and if its in water and its liquid how does the iceberg float?
Water is unusual in that as it freezes it expands, thus water's density is less when a solid than as a liquid, interestingly water is most dense around 4C.
