evaporation - changes liquid to gas eg water to steam, condensation - changes gas to liquid eg steam to water, freeze - changes liquid to solid eg water to ice, melt - changes solid to liquid eg ice to water, solid particles - particles are arranged neatly, can only vibrate, liquid particles - particles are able to move freely, but are still touching, gas particles - move around fast, not touching, bouncing off things, states of matter - solid, liquid and gas, dissolving - something disappearing into a solution, solute - the thing that dissolves eg salt, solvent - the liquid that a solute dissolves in e.g. water, solution - solute + solvent eg salt water, insoluble - something that does not dissolve eg sand, soluble - something that dissolves eg sugar, filtering - separates insoluble solids from liquids eg sand from water, evaporating (separation) - separates soluble solids from liquids eg salt from salt water, distillation - evaporation followed by condensation. Used to separate things like ink from water., chromatography - separates mixtures of soluble solids e.g colours in ink, mixture - several things together, but not chemically joined, compress - squeeze to make smaller (only gas), sublimation - solid to a gas, deposition - gas to solid, diffusion - Movement of molecules from an area of higher concentration to an area of lower concentration.,
