The picture/images of the different seprating mixtures Decantation,Filtration, Evaporation,Distillation,Magnetism, Chromatography,Sieving,Sifting, Winnowing,Handpicking​

Here's a breakdown of the separation techniques you listed, with explanations and visual aids where possible:1. Decantation: What it is: Separating liquids from solids (like sediment) or immiscible liquids (like oil and water) by carefully pouring off the top layer after the heavier component has settled.How it works: Relies on gravity to separate substances with different densities.Example: Separating sand and water, or oil and water.2. Filtration: What it is: Separating solids from liquids or gases using a porous barrier (filter) that allows the fluid to pass through but retains the solid particles.How it works: Uses a filter paper or other material with pores too small for the solid particles to pass through.Example: Separating tea leaves from brewed tea, or filtering muddy water.3. Evaporation: What it is: Separating a dissolved solid from a liquid by heating the mixture until the liquid evaporates, leaving the solid behind.How it works: Exploits the difference in boiling points between the liquid and the solid.Example: Separating salt from salt water.4. Distillation: What it is: Separating liquids with different boiling points by heating the mixture, collecting the vapor of the liquid with the lower boiling point, and then condensing it back into a liquid.How it works: Involves vaporization and condensation.Example: Separating alcohol from a water-alcohol mixture.5. Magnetism: What it is: Separating magnetic materials from non-magnetic materials using a magnet.How it works: Exploits the magnetic properties of certain materials.Example: Separating iron filings from sand.6. Chromatography: What it is: Separating components of a mixture based on their different affinities for a stationary phase and a mobile phase.How it works: The mixture is dissolved in a fluid (mobile phase) and passed over a material (stationary phase).Example: Separating different pigments in a plant extract.7. Sieving/Sifting: What it is: Separating particles of different sizes using a mesh or perforated surface.How it works: Particles smaller than the mesh openings pass through, while larger particles are retained.Example: Separating sand from gravel, or flour from lumps.8. Winnowing: What it is: Separating lighter particles from heavier ones by throwing the mixture into the air, allowing the wind to carry away the lighter material.How it works: Relies on differences in density and wind resistance.Example: Separating chaff from grain.9. Handpicking: What it is: Manually separating desired components from a mixture based on visual differences.How it works: Relies on human observation and selection.Example: Picking out bad apples from a basket of apples.
