Explanation:
Physical properties such as size, shape, color, density, magnetism or the
ability to sink or float can be used to separate the substances in a mixture..
Filtration is when matter is passed through a filter and the larger particles
are separated out. Magnets can be used to separate magnetic matter from
non-magnetic matter in a mixture. Objects that float when placed in water
can be separated from those that don’t by placing the mixture in water.
