Solid, liquid and gas

Floating iceberg.

Water is the only common substance that is naturally found as a solid (ice), liquid (water) or gas (water vapour in the atmosphere). It’s also unusual because its solid form (ice) is less dense than its liquid form. That’s why this iceberg is floating on the surface of the sea.
