which of the following properties of ice causes it to be less dense than liquid water so that ice can float on top of liquid water?
high specific heat capacity
polar covalent bonds in water
adhesion and cohesion
lattice structure due to stable hydrogen bonding

Explanation:

When water freezes, hydrogen bonds form a lattice structure. In this lattice, water molecules are spaced farther apart than in liquid water. Density is mass per unit volume. With more space (larger volume) between molecules in ice (for the same mass compared to an equal - mass sample of liquid water), ice has a lower density. High specific heat capacity relates to heat absorption, polar covalent bonds are about electron sharing in water molecules, and adhesion (attraction to other substances) and cohesion (attraction between water molecules) do not directly explain the density difference between ice and liquid water.

Answer:

lattice structure due to stable hydrogen Bonding
