The methods that separate a mixture according to the size of the particles are filtration and evaporation.
- Filtration works by using a filter to separate solid particles from a liquid or gas based on size.
- Evaporation, while primarily used to separate a solute from a solvent by turning the solvent into vapor, can indirectly involve size if the solute remains as solid particles after the solvent evaporates.
However, in the context of methods that primarily focus on particle size, the main method is filtration. Among the options provided, the correct answer is filtration but the second component (evaporation) does not specifically separate based on particle size alone.
If the primary comparison is strictly about methods separating mixtures by particle size, filtration is the key method here.
