Name any two methods used to separate:

 Solid-solid mixtures:
Two methods used for separating solid-solid mixtures are:

• Hand picking – Used when one component is present in small quantity and can be easily picked out by hand (e.g., removing stones from rice).
• Winnowing – Used to separate lighter particles from heavier ones using wind (e.g., separating husk from grains).

(b) Liquid-solid mixtures:
Two methods used for separating liquid-solid mixtures are:

• Filtration – Used to separate insoluble solids from liquids (e.g., separating tea leaves from tea).
• Evaporation – Used to separate dissolved solids from liquids (e.g., obtaining salt from saltwater).
