Detailed Solution

Concept: Ice is water in its solid state, with the same hydrogen and oxygen atom composition as water. When the temperature drops, the density of water usually rises. However, water behaves strangely at 4°C; as the temperature drops below 4°C, the density decreases rather than increases. This is why ice is less dense than water at 0 degrees Celsius.
What distinguishes ice from other liquids is that the structure of water molecules in liquid form differs from that of water molecules in solid form. The arrangement of water molecules in the solid phase (ice) follows a regular pattern, whereas there is no such pattern in the liquid phase.
Hence, the correct option is 1.
