The difference in density between the two substances can be attributed to hydrogen bonding. In the solid state, molecules of H₂O are held together by hydrogen bonds while the molecules of H₂O( 11ea8937_ab71_cd3a_a16d_d7c182fa1e3f_TB4499_11 ) are not. Hydrogen bonding is a strong intermolecular force that results from the attraction between partially positively charged hydrogen atoms (in one molecule) and negatively charged atoms (in another molecule) such as oxygen in this case. This strong intermolecular force makes H₂O more closely packed in solid form than in solution which leads to its higher density.
