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 .
increases, reaching its maximum density at 4°C. Below 4°C, water expands as it freezes, forming ice which is less dense than liquid water.

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.
Explain the fact that the temperature of the ocean at great depth is very constant the year round at the temperature of about 4C?
The deep ocean temperature remains constant year-round at around 4°C due to a lack of sunlight reaching those depths, which prevents seasonal temperature fluctuations. Additionally, the density and volume of water at depth slow down the rate of temperature change. The 4°C temperature is a result of water's maximum density occurring at that temperature.
You want 1 kg water convert in liter?
1 kg of water is equal to 1 liter, as the density of water is 1 kg per liter. So, 1 kg of water is equivalent to 1 liter.
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?
Yes, if some of the liquid evaporates, the density of the remaining liquid will increase because the evaporated components are typically lighter than the liquid itself. This means that there is a higher concentration of the heavier components left behind, leading to a higher overall density.
What is the normal freezing point of heavy water?
The normal freezing point of heavy water, which is deuterium oxide (D2O), is around 3.8 degrees Celsius (38.8 degrees Fahrenheit). This is slightly higher than the normal freezing point of regular water (H2O) due to the heavier isotope of hydrogen used in heavy water.
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

The Temperature at which water possesses maximum density is?
The temperature at which water possesses maximum density is 4 degrees Celsius. At this temperature, water molecules are packed closely together, decreasing the volume per molecule and increasing the density.
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
Explain what happens to volume as water temperature goes from 4C to 0C and freezes.?
As water temperature decreases from 4°C to 0°C, the volume of the water decreases slightly as it approaches its maximum density at 4°C. When water freezes at 0°C, it expands about 9% in volume, which is why ice is less dense than liquid water.
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.
Why does all the water in lake have to be cooled to 4c before surface water can be cooled below 4c?
Water is most dense at 4 degrees Celsius. When cooling the surface water below 4 degrees Celsius, the colder water sinks because it is denser, causing a uniform temperature to be established at 4 degrees Celsius throughout the lake before further cooling can occur. This uniformity is necessary to prevent a temperature gradient that could disrupt the natural mixing patterns of the lake.
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?
An iceberg floats because it is less dense than the water it displaces. When ice forms, it expands and becomes less dense than liquid water, allowing it to float. This buoyancy force counteracts the downward force of gravity, keeping the iceberg afloat.
Why does water attain its maximum density at 4 degrees Celsius?
Water reaches its maximum density at 4 degrees Celsius because this is the temperature at which the hydrogen bonds in water arrange themselves in a way that allows for the most efficient packing of water molecules. Below 4 degrees Celsius, the hydrogen bonds lock water molecules into a lattice structure, causing an expansion in volume.
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.
