Solids, liquids and gases. In a solid like this brick, the particles are regularly arranged touching their neighbours and move only by vibrating. This explains why solids have a fixed shape.

Dissolving a solid in a liquid depends on the interactions and attractions between the molecules of the liquid (solvent) and the particles of the solid (solute). Dissolving happens when the attraction ...

With properties of a superfluid but with a crystalline structure, supersolids have previously only been observed in ultracold ...

The size of particles found in a colloidal dispersion range between 1 and 1000 nanometres. The two components are referred to as the dispersed phase and continuous phase respectively. Either phase can ...
