States of Matter: Liquids — three ways to learn it.

The complete written lesson — intermolecular forces (dipole–dipole, London, hydrogen bonding), evaporation, vapour pressure, boiling point, surface tension, viscosity, capillarity and the heats of phase change.

As you scroll, a live D3 panel animates every idea: a hydrogen-bond network in water, evaporative cooling, boiling bubbles, surface tension, viscosity races, and a vapour-pressure simulator where you heat the liquid and watch the pressure climb to boiling.

Explore evaporation, boiling and the properties of liquids on a safe, virtual bench. All of the course's hands-on experiments live here, organised by chapter.
