This summary provides a clear explanation of nine common separation techniques, including decantation, filtration, evaporation, distillation, magnetism, chromatography, sieving/sifting, winnowing, and handpicking, highlighting how each method works based on the different properties of the mixture components and how it is used in practical applications. Key points about each technique:Decantation:Relies on density differences to separate liquids from solids or immiscible liquids by allowing the denser component to settle and then carefully pouring off the lighter liquid.Filtration:Uses a porous barrier to trap solid particles while allowing liquids or gases to pass through, based on particle size.Evaporation:Removes a liquid from a mixture by heating it, leaving the solid residue behind.Distillation:Separates liquids with different boiling points by vaporizing the mixture, collecting the vapor of the lower boiling point liquid, and then condensing it back into a liquid.Magnetism:Uses a magnet to attract magnetic materials, leaving non-magnetic materials behind.Chromatography:Separates components of a mixture based on their different affinities for a stationary phase and a mobile phase.Sieving/Sifting:Uses a mesh to separate particles based on their size, with smaller particles passing through the mesh and larger particles being retained.Winnowing:Relies on wind to separate lighter particles from heavier ones by throwing the mixture into the air.Handpicking:Manually selecting desired components from a mixture based on visual observation.
