Water is strange stuff. The density of all water at the same temperature is the same.
But as water cools down it gets denser and denser and sinks down through warmer water.
But ... when water reaches 3.98 C it starts to get less dense again and rises through slightly warmer water
As result the water at the surface of a lake is lighter and colder than the liquid at depth. In that location it can reach 0 C and freeze. the ice formed is about 90% as dense as water and floats.
As a result the open bodies of water freeze from the top down not the bottom up.
This is convenient for fish who can continue to live in the water under the ice and not be frozen out to the surface of the ice accumulated at the bottom.
The physics of this are complex but it relates to the initial formation of proto-ice cluster at 3.98 C which are lighter than liquid water and reduce the overall density of the mixture.
yes liquid water is more dense than ice water
Ice cubes are less dense than liquid water, which is why they float.
Liquid water is more dense than ICE , and More dense than water vapour(steam). Liquid water is at its most dense at 2 oC. Water on freezing to ice expands by about 10% of its volume. This is because of the lattice arrangement of water molecules in ice., which does not occur in liquid water., Hence ice floats on water. (icebergs).
Less dense. For most substances, the solid form is more dense than the liquid form; water is a notable exception.Less dense.

No. Liquid water is more dense. This is why ice cubes float on liquid water.
Ice water is more dense than warm water.
That depends on the specific situation. Assuming the liquids just mix, and don't have some other reaction: * Adding water to a liquid that is denser than water will result in a liquid that is less dense (than the liquid that is not water). * Adding water to a liquid that is less dense than water will result in a liquid that is more dense.
No, it will only float in a liquid more dense than it. Since it is more dense than water, it would sink in water, for example.
Ice is less dense than liquid water, and liquid water is more dense than water in the gaseous state.
Solid water, ice, is less dense than its liquid state. This is essential for aquatic life. Since ice is less dense than liquid water, it floats to the top of of the water. This insulates the water beneath the ice, allowing the water beneath the ice to remain liquid. For other substances, the solid state is more dense than the liquid state.
At room temperature and pressure, water is more dense than CO2. If CO2 is cooled and compressed to a liquid, it is more dense than water.
Water is most dense at +4 Celsius. This is why lakes do not freeze to the bottom at winter. Solid ice is less dense than water.
