What you'll learn
Why solids, liquids and gases behave differently, explained by how their particles are arranged and how much they move - and what actually happens to those particles during melting, boiling and the other changes of state.
- The three states, explained by particle arrangement
- Particles are always moving, and hotter means faster
- Melting and freezing: solid ↔ liquid
- Boiling and condensation: liquid ↔ gas
- Evaporation is not the same as boiling
- Sublimation skips the liquid state entirely
- Diffusion happens because particles are always moving and spreading out
