Detailed explanation-1: -The water expands as it freezes, which breaks the bottle.
Detailed explanation-2: -Most liquids contract as they freeze, making their solid form denser than their liquid form. Unlike virtually every other liquid, however, water expands when it freezes, making frozen water less dense than liquid water. That’s why ice floats. This special property of water helps preserve it in its liquid state.
Detailed explanation-3: -Water is a unique substance because its solid state-ice-is less dense than its liquid state. Physical properties are characteristics of a substance. They do not change. Physical properties include color, smell, freezing/melting point, and density.
Detailed explanation-4: -When liquid water (H2O) freezes into a solid state (ice), it appears changed; however, this change is only physical, as the composition of the constituent molecules is the same: 11.19% hydrogen and 88.81% oxygen by mass.
