The methods that separate a mixture according to the size of the particles are primarily A. Filtration and evaporation.
-
Filtration is a method used to separate solids from liquids or gases using a filter medium that allows only the fluid to pass through while retaining the solid particles based on their size.
-
Evaporation is typically used to separate a solute from a solvent in a solution, but it doesn't separate based on particle size.
Chromatography (as mentioned in option C) is mainly used to separate components of a mixture based on their movement through a stationary phase and is not primarily based on particle size.
So, the best choice specifically focusing on particle size separation would be A. Filtration (with the understanding that evaporation doesn't separate by particle size).
