Ice is a solid , water is a liquid then why does ice float on water? please explain in detail.?

Answer 1

An unusual feature of ice frozen at a pressure of one atmosphere is that the solid is some 8% less dense than liquid water. Ice is also one of the few substances to expand when it freezes. Ice has a density of 0.917 g/cm³ at 0 °C, whereas water has a density of 0.9998 g/cm³ at the same temperature. Liquid water is most dense, essentially 1.00 g/cm³, at 4 °C and becomes less dense as the water molecules begin to form the hexagonal crystals of ice as the temperature drops to 0 °C. (In fact, the word "crystal" derives from Greek word for frost.) This is due to hydrogen bonds forming between the water molecules, which line up molecules less efficiently (in terms of volume) when water is frozen. The result of this is that ice floats on liquid water, an important factor in Earth's climate. Density of ice increases slightly with decreasing temperature (density of ice at −180 °C (93 K) is 0.9340 g/cm³).

Answer 2

Water expands when it freezes into ice. Ice is less dense than water, thus it floats.

Answer 3

since density of ice is less than water therefore it floats on water

Answer 4

Water is the only liquid on earth which decreases in density when frozen.

Answer 5

water is polar & the molecules repel each other as they slow/cool to become a solid. expanded ,it floats as ice.

Answer 6

the density f ice is 0.9 whereas for water it's 1

Answer 7

Because of the oxygen trapped inside. H2o
