Ice: Water in its solid state, which has a fixed shape and size.

Water (liquid): The most familiar form of water, which is wet, fluid, and takes the shape of its container without a fixed shape or size.

Water Vapour: Water in its gaseous state, which does not have a fixed shape or size and fills all available space.

Melting: The process in which a solid changes into a liquid on heating.

Evaporation: The process in which a liquid changes into vapours (gaseous state) on heating.

Condensation: The process in which a gas changes into a liquid on cooling.

Solidification: The process in which a liquid changes into a solid.

Freezing: The process in which water changes into ice; it is the reverse of melting.

Sublimation: The conversion of a solid to a gas without passing through the liquid phase.

Deposition: The direct solidification of vapor into a solid.

Solution: A mixture in which a solute dissolves in a solvent at a particular temperature.

Solute: The substance that dissolves in a solvent.

Solvent: The substance in which the solute dissolves.

Universal solvent: A substance (like water) that dissolves most other substances.

Soluble substances: Substances that dissolve in a solvent to form a solution.
