Why would Ice float on the water when the ice is heaver than the water?

Question

Like there's 6 water molecules in the water. When tempure drop, the water froze into ice. There will still have 6 molecules in the ice, the y they will ice float on the water?

Answer 1

Ice is less dense than water.

Answer 2

No ice would not float on water when ice is heavier than water.

( In reality water is heavier than ice )

This i do not understand :

Answer 3

Each water molecule has 2 hydrogen atoms attached to a single oxygen atom (H2O). Water molecules are very polar. This means that they have a slightly positive (the hydrogen side) and a slightly negative (the oxygen side) end. When water is warm enough to be a liquid, the molecules have enough energy to overcome this attraction. As they cool, this attraction (positive end of one to negative end of next molecule) causes them to form ice crystals which take up more space than the "warmer" molecules of the liquid which can be closer together and overcome this attraction between water molecules. Since you have the same number of water molecules, the mass does not change. As the space increases, the volume increase. Increasing the volume while keeping the mass constant will cause the density to decrease. (Density = mass divided by volume).

Thus, ice is less dense than liquid water. Less dense objects flost in more dense objects. Therefore, ice floats on water.

Interesting to note...H2O is rare in that its solid floats on its liquid. It is the case with most substances that their solids will sink in their liquids. Example: Solid iron will sink in molten (liquid) iron.

Answer 4

Each water molecule is made of 2 hydrogen atoms and 1 oxygen atom. These are connected to one another by very strong chemical bonds called covalent bonds. Water molecules are connected to each other by much weaker chemical bonds called hydrogen bonds between the positively charged hydrogen atoms, and one negatively charged oxygen atom in a neighboring water molecule.

As water gets colder than 4 degrees Celsius (40 Fahrenheit) the hydrogen bonds connecting different water molecules adjust to keep the negatively charged oxygen atoms apart. This results in a crystal latice which begins to form at less than 4 degrees Celsius. This crystal latice is completely formed at freezing, and is commonly known as ice.

So, why does ice float? Like most things that float, ice floats because it is less dense than liquid water. Ice is about 9% less dense. When ice forms, it takes up about 9% more space than it did as a liquid. Thus, a 1 liter container of ice weighs less than a 1 liter container of liquid water, and the lighter material floats to the top. As we said, water is different.

Answer 5

Because they form a crystal lattice which occupies more volume that the 6 molecules when they were free to assume any configuration they wanted. As a result, the density of ice is less than the density of water and the ice floats.

Answer 6

Yes water is less dense than water. It depends upon the size of the ice that your saying. If the water you're asking is an ocean or a sea, then the water is denser that that ice. One more thing, ice is made up of water. (never mind my answer)

Answer 7

Water have the highest density at 4 degree Celcius.

Answer 8

ice is less dense dan water. dats y it floats

Answer 9

Ice is slightly lighter than water because it expands just before it freezes. .

Answer 10

no water is heavier. the proof is that ice floats on water
