Question

Ice has a lower density than water because ice A) is made of open structured, hexagonal crystals. B) sinks C) density decreases with decreasing temperature

Answer 1

The ice has density which is lower than water because

As the water freezes, water molecules form a crystalline structure making the hydrogen bonding more stronger than that of the liquid. The orientation of the hydrogen bonding pushes the water molecules farther apart which reduces the density.

Because ice is less dense than water, it is able to float at the surface of water.

Hence the lower density of ices is due to the crystaline structure of ice

Hnece option A is the correct choice
