Question

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

Answer 1

because the property of water is different materials is different from other elements
it contracts on heating and expandable on cooling

Answer 2

As it cools further and freezes into ice, it actually becomes less dense. On the other hand, most substances are most dense in their solid (frozen) state than in their liquid state. Water is different because of hydrogen bonding. ... The heavier water displaces the lighter ice, so ice floats to the top.
