Question

why the density of ice is lower yhan that of water​

Answer 1

Explanation:

Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density. ... When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Solid water, or ice, is less dense than liquid water.

Answer 2

Answer:

we know that at 4degree Celsius instead of contracting ;water begins expanding.. this nature of water is called ""anomalous expansion of water"". due to this reason the density of ice reduces ..so ice floats on water

Explanation:

due to expansion the intermolecular distances were increases and density becomes reduced.........
