What are the three forms of water?

Water can occur in three states: solid (ice), liquid or gas (vapor).

  • Solid water – ice is frozen water. When water freezes, its molecules move farther apart, making ice less dense than water.
  • Liquid water is wet and fluid.
  • Water as a gas – vapor is always present in the air around us.
