Water is most dense at about 3 degrees C at which time if it is in a fresh water lake it wil sink to the bottom of the lake. Typically, when the entire lake turns to 3 degrees the top layer of water cools and expands and freezes and that's why ice floats...thank goodness or we would have no hockey.

How do you find density of an object in water?
If the object floats it is less dense than water, if it submerges it is denser than water.
Why do things float?
Because they are less dense than the water. We call the amount of mass in a given volume of space the density. For instance, we could measure the mass of some fresh water in a container. We would then divide the mass of the water by the volume of the container to find the density. However, if we filled the same container with salt water, it would have more mass because the ocean water has the mass of pure water plus the mass of the salt. Since there is more mass in the same volume, ocean water has a greater density then fresh water. For something to float, it must have a density that is less than in what it is floating in. It may seem odd that an enormous ship can float when steel is denser than water. However, if you look at the entire ship you see that there are many places filled with things less dense than water, like air. This means that the density of the entire ship is less dense than that of the water it floats in. To understand why things less dense then water float in water go to the question "Why do some things float but not others?" in the Related Questions section below.An object floats because it is less dense than whatever it is floating in.
Is wool good insulator?
Yes wool is a good insulator because it is dense. That's why sheep's wool is fluffy, because it's dense. You can find this at farms!!!!!!!
What would happen if you tried to find the density of an object with a density less than water?
If an object was less denser than water it would float
Is diamond heavier than ordinary stone?
Yes. Its specific gravity is 3.52±0.01, meaning that is that much more dense than water, which is the base for specific gravity -- or weight. You can find comparitive stones on the chart, below.
How dense is Saturn?
Saturn is the least dense of all the Planets. It has been said that if you could find a large enough bath - and water, Saturn would float. This is because Saturn's mean density is lower than water at 0.687 g/cm³
In which layer of earth would you expect to find the least dense materials?
The crust is the least dense portion of the solid Earth because it is the thinnest layer.
Where would you find the least dense elements in a star?
Denser elements in a star tend to condense near the star's core, while less dense elements generally move outward towards the surface to take place in nuclear fusion.
Is this true or false water is more dense in its solid form than it is in its liquid phase?
Technically it's neither true nor false without additional information (we would need to know the temperature and pressure). However, for "ordinary" conditions that you might find on or near the surface of the Earth, ice (solid water) is less dense than water (liquid water).
How do you find density of an object in water?
If the object floats it is less dense than water, if it submerges it is denser than water.
Where would a developer be most likely to find a sufficient supply of water for a network of wells for a community?
They would find it around the plains or at least around a waterfall so they can clean it.
Where in the centrifuge tubes would you find the heavy parts of the blood?
The bottom as it is more dense
Where would you find the most dense layer of the earth?
The center of the planet. The Inner Core.
Where in Earth you would find the highest concentration of dense metals such as iron?
outer core
What materials you need to find what type of water contains the least amount of chlorine?
find cups of water
Are gases more dense than solids?
No, gasses are far less dense that solids. Gasses are the least dense of the three common states of matter.
Where would you find the lowest density in seawater?
Answer 1) At the Surface. Answer 2) I disagree with the above answer. For practical purposes water is not compressible. Therefore the density is the same all over. The difference in density at the surface and at the bottom is so small that it is negligible. However, fresh water is less dense than seawater, since the salts dissolved in the seawater makes it more dense. For that reason, if you consider seawater near the mouth of a river, that water will be less dense than the seawater in general.
