liquid water is less dense

none of the above

Detailed explanation-1: -Ice is less dense than water This is due to ice’s density being less than liquid water’s density. Upon freezing, the density of ice decreases by about 9 percent.
Detailed explanation-2: -The solid form of most substances is denser than the liquid phase so a block of most solids will sink in the liquid but a block of ice floats in liquid water because ice is less dense. Upon freezing the density of water decreases by about 9%.
Detailed explanation-3: -The increase distance between water molecules in solid water is the reason solid water is less dense than liquid water.
Detailed explanation-4: -Therefore, the density of water vapor is much lower than the density of solid or liquid water. In most substances, the solid phase has a higher density than the liquid phase because the well-ordered crystal structure allows the constituent particles of the substance to be efficiently packed together.
