∙ 15y agoIn a cold winter, cold air cools the surface of a pond or lake. If ice were more dense than water it would immediately sink to the bottom. More water at the surface would freeze and sink, soon resulting in a pond full of solid ice and dead fish. As it is ice floats, and the pond acquires a lid of ice. Ice is a poor conductor of heat, so the ice thickens only slowly, and the thicker the slower. The fish live on. Note. The density of ice is not the whole story; by a strange quirk of fate water's change of density with change of temperature is anomalous. Most substances get steadily more dense as they cool. Water does this only till about 4 deg C ; then the density starts to decrease again. This means that the process of convection, which might otherwise repeatedly send cold water to the bottom, resulting in a large iced lollipop ( fish-flavoured ) doesnt happen. The fish survive.

∙ 9y agoWhen temperature falls below freezing point a layer of ice is formed on the lake. As ice is less denser than water, this layer of ice floats above the water surface. Ice is bad conductor of heat, it prevents freezing of the water below it. Therefore the water inside the lake is in liquid state helping fish and other water living beings to live.

Does ice float because water becomes more or less dense when its frozen?
The structure of frozen water (ice) is less dense than the random arrangement of the water molecules in liquid water, thus ice floats because water becomes less dense when it is frozen. Because of buoyancy forces, an object placed in a liquid will float if it is less dense than the liquid and sink if it is more dense.
Is a rubber ducky more dense then water?
no beacause a rubber duck floats and if an object floats in water, is is less dense than the water if it sinks it is more dense
How can you determine weather a solid substance is more dense or less dence than water?
put them both in a tub of water and if one floats its not as dense as the other if it sinks its more dense
Does ice floats in Mercury?
Yes. Ice floats in water because it is less dense. Mercury is over ten times denser than water. So ice easily floats in mercury.
Does pumice floats in water?
Porous lava rock is called pumice. If placed in water, it would float as it possesses a density that is less than water.
Wood floats on water because it?
because it is less dense
Why a porcuspine floats in the water?
because it is less dense.
Why ice floats in in water?
The reason why ice will float in water is because ice is not as dense as water, therefore, it floats.
Why does bark float in water?
it floats on water because bark contains air Bark floats in water because it is less dense than water.
Why do you think water is less dense when frozen and more dense at room temperature?
because ice floats on water
Why does a mandarin float on water?
It floats on water because it is less dense than the water.

Do cornoil float on water?
Corn oil floats on water. It floats because oil is less dense than water. When one substance is less dense than another it rises to the top.
Why does dust float?
Dust floats in water because it is less dense than the water.
Which oil sink in water?
No. Oil floats on water because it is less dense than water.
Why does a body float in water?
A body floats in water because it is less dense than water.
Why air floats when it has weight?
Because it is less dense than the water/liquid.
