liquid generally have lower density as compared to solids but you must have observed that ice floats on water find out why

as the substance freezes it becomes less denser so ice floats on water even if it is a solid

in ice each oxygen atom is surrounded tetrahedrally by four other oxygen atoms at a distance of 276pm.
Moreover each oxygen atom is surrounded by four hydrogen atoms , two connected by covalent bond and two by hydrogen bonds.
Due to extensive hydrogen bonding the resulting structure of ice is "open cage like structure" having a number of vacant spaces. Thus less number of molecules are packed per ml. Melting in ice results in breaking of hydrogen bonds. In this way the molecules come close to each other in the liquid state than they were in the solid state. Thus ice has lower density than water.
hope this answer may clear your doubt...
