Question

solid water is less dense than liquid water. false true rewatch submit

Explanation:

Water has a unique property. When it freezes into ice (solid water), the hydrogen - bonding network causes the water molecules to arrange in a more open, hexagonal lattice structure. This increases the volume of the solid compared to the liquid for the same mass of water. Since density is mass per unit volume ($\text{density}=\frac{\text{mass}}{\text{volume}}$), with mass remaining constant and volume increasing in the solid state, solid water (ice) is less dense than liquid water.

Answer:

True
