Why is it important to living things that water is less dense a solid than as a liquid?

Water has an absurd property; instead of getting compressed below -4 degrees celsius it starts to expand. This leads to a decrease in density which allows the solid ice to float on water. Thus, insulation is provided to the aquatic animals below these ice sheets in frozen ponds, lakes etc. Were it not for this property the whole water body would freeze and kill all the aquatic life as the ice would sink and bring more water up to freeze.

∙ 10y agoIt is not so much an advantage as a charastice that facilitates the existance of life as we know it. Because ice (solid water) is less dense than liquid water, ice floats on water and acts as an insulator, facilitating the continuing existance of liquid water under it. This permits life forms to survive through the very cold months without having to develop the rare and very difficult ability to survive being frozen.
If ice were more dense than water, it would sink below the water as it froze, exposing more water for freezing. And during the thaw, the top layer of liquid water would insulate the ice below, making it last longer, or perhaps never melt, even in what we now think of as temperate climates.

∙ 6y agoSolid water (ice) would need to be heated to return to the liquid water stage. Further heating would boil the liquid water into water vapour, and water vapour is less dense than liquid water. Basically, it is all a matter of applying heat, either artificial heat from gas or electricity, or naturally using the heat from the sun.

Well it not important but like the molecule in the water of a solide water aare far apart from each other but in a liquid state the molecule are closer together.Density is a meaure of how CLOSE moleculesare to each other.

Which is denser water or the same water that formed into an ice tube?
Liquid water is denser because when water freezes, the water particles spread out as they solidify. This means that the same amount of particles take up more space, causing the density to decrease. Ice is less dense also because ice cubes float on liquid water. Less dense things float on more dense things.
The tendency of a less dense substance to float in a more dense liquid is called what?
The tendency of a less dense substance to float in a more dense liquid is called buoyancy. Acids are substances that form hydronium ions when dissolved in water.
How would you verify the Archimedes principle for objects that are less dense than the liquid?
Two ways to do this: 1) Floating the less dense object on the more dense liquid. To verify the Archimedes principle you need to show that the mass of the liquid displaced by the less dense object is equal to the mass of the less dense object. To do this you need to have a way to determine the mass of the displaced liquid. If the liquid is in a container filled to the brim, then when you place the less dense object in it, the displaced liquid will spill out over the edges of the container. If you can collect and weight that liquid, then you can compare its weight to the weight of the less dense object - they should match. Alternatively, you can find a way to measure the volume of the displaced liquid and calculate the mass from the volume and density of the displaced liquid. 2) Immerse the object completely in the liquid and measure the force required to keep it submerged. This one is more complicated and difficult to execute and measure. The force required to keep the less dense object submerged should be the difference between the weight of the object (when it is not in the liquid) and the weight of the displaced liquid.
What is an example of a solid that Is less dense than a liquid?
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.

Why do heavy things sink?
Not all heavy things sink. Things that are more dense than the liquid around them will sink.
Why does tree wood float?
Things float because they are less dense than the liquid they are in.
What does the statement 'the buoyant force of a liquid does not depend on physical statebut on density' mean?
Floating, or buoyancy, depends on the density of the liquid and the density of the object. Water is a pretty dense liquid, and things float in it; they are buoyant. Oil or gasoline are less dense; things that float in water may not float in oil.
Where will the dense liquid be found?
The least dense liquid would be found at the top.
Would water or liquid mercury float?
Water floats when it is turned into ice, because in this form it is less dense (it crystallizes, and the structure expands). It also can float in combinations of liquids, for example, it is less dense than liquid mercury, but more dense than oil, so it would 'float' on the mercury. Liquid mercury is very dense, and doesn't usually float on things.
Is liquid magma less dense or more dense?
Liquid magma is more dense than the solid material around it.
Why does one liquid float on one another?
The liquid which is less dense will float on top of the liquid which is more dense. Density affects the liquid's level.
Do heavy things always sink and light things always float?
It depends on the density of the liquid the object is immersed in and also the density of the object itself. If the liquid is more dense then the object, it will float.
Is liquid water less dense than ice cubes?
No. Liquid water is more dense. This is why ice cubes float on liquid water.
Does adding water to a liquid make it less dense?
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.
Which cold solid is less dense than the liquid when it melts?
Ice is a solid less dense than the liquid
