The ice floats on water becausea)its density is more than waterb)its density is less than waterc)it has less intermolecular spaced)none of the aboveCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

It's density is less than water as its inter molecular space is filled by gases hence volume increases.
Density and volume are inversely proportional

Answer

During the process of solidification in which water in form of liquid changes to solid state , some empty spaces are created in between the particles of the matter. So due to intermolecular spaces in ice , it floats on water .

Answer

**Explanation:**

When ice floats on water, it means that ice is less dense than water. This is due to the unique structure of water molecules and the behavior of hydrogen bonding.

**Structure of Water Molecules:**

Water is composed of two hydrogen atoms bonded to one oxygen atom (H2O). The shape of a water molecule is bent or V-shaped, with the oxygen atom at the center and the hydrogen atoms bonded to it. The oxygen atom has a slightly negative charge, while the hydrogen atoms have a slightly positive charge.

**Hydrogen Bonding:**

The oxygen atom in a water molecule is capable of forming hydrogen bonds with neighboring water molecules. Hydrogen bonding occurs when the slightly positive hydrogen atom of one water molecule is attracted to the slightly negative oxygen atom of another water molecule. This creates a network of hydrogen bonds between water molecules.

**Effect of Hydrogen Bonding on Density:**

In the liquid state, water molecules are constantly moving and forming and breaking hydrogen bonds with neighboring molecules. This allows water to have a relatively high density compared to other liquids.

However, when water molecules freeze and form ice, the hydrogen bonds become more stable and ordered. The water molecules arrange themselves in a hexagonal lattice structure, with each water molecule forming hydrogen bonds with four neighboring molecules. This arrangement causes the water molecules to be more spread out, resulting in an increase in volume and a decrease in density.

**Density Comparison:**

The decrease in density when water freezes is the reason why ice floats on water. The density of ice is about 0.92 g/cm3, while the density of liquid water is about 1 g/cm3. As a result, ice is less dense than water, causing it to float.

**Conclusion:**

In conclusion, ice floats on water because its density is less than that of water. This is due to the unique structure of water molecules, the formation of hydrogen bonds, and the expansion of water when it freezes.

Answer

Ice has leas density that is why it floats on water and if something like an iron nail which has more density then it will definitely sink in water

Answer

During freezing of ice , some air gaps are formed which are called fine structures which lower the the density of water due to increase in volume.So ice has lower density than water and it floats on water surface.

Answer

B ) its density is less than water.

Answer

A

Answer

When water cools, the hydrogen bonds adjust to hold the negatively-charged oxygen atoms apart, which prevents the ice from becoming any denser. So for water, the density actually decreases along with a decrease in temperature - causing ice to be less dense than water!
