how do you separate materials using physical properties?
There are several physical properties that can help you separate material: -magnetism: you can separate magnetic from non-magnetic material (magnetic would stick to a magnet) -density: you can separate materials with different densities by putting them into a liquid with a specific density, Those denser than the liquid would sink, the others float -melting or evaporation point: you can submit a mixture of substances to specific temperatures, so that only one type would melt or evaporate That's about what I can think of now. Hope it helps!
