Physical separation methods are techniques used to separate mixtures based on their physical properties without changing their chemical composition. Common methods include filtration, where solids are separated from liquids using a filter, and distillation, which separates liquids based on differences in boiling points. Other methods include centrifugation, which uses rapid spinning to separate components by density, and magnetic separation, which utilizes magnets to remove magnetic materials from mixtures. These methods are widely used in various fields, including chemistry, environmental science, and food processing. They are essential for purifying substances, recycling materials, and analyzing samples in laboratories.
