Why ice floats over water? |
|
Answer» https://www.zigya.com/share/Q0hFTjExMDg3MzQz Ice floats on water because it\'s density is lesser than water Ice floats on water because of the anomalous expansion of water after 4°C........HOPE IT HELPS...... In the solid state (ice), intermolecular interactions lead to a highly ordered but loose structure in which each oxygen atom is surrounded by\xa04\xa0hydrogen atoms; two of these hydrogen atoms are covalently bonded to the oxygen atom, and the two others (at longer distances) are hydrogen bonded to the oxygen atom’s unshared electron pairs.this open structure of ice causes its density to be less than that of the liquid state, in which the ordered structure is partially broken down and the water molecules are (on average) closer together. When water freezes, a variety of structures are possible depending on the conditions.\xa09\xa0different forms of ice are known and can be interchanged by varying external pressure and temperature. |
