Question

sort these real - world examples by separation technique. items (5 items) (drag and drop into the appropriate area below) removing dust particles from the air preparing gasoline from crude oil separating coffee grinds from water preparing drinking water from seawater categories filtration distillation chromatography

Explanation:

Step1: Recall filtration principle

Filtration separates solids from liquids or gases by passing through a porous medium. Removing dust particles from air (using air - filters) and separating coffee grinds from water (using coffee filters) are filtration processes.

Step2: Recall distillation principle

Distillation separates components of a mixture based on differences in boiling points. Preparing gasoline from crude oil (fractional distillation) and preparing drinking water from seawater (simple or multi - stage distillation) are distillation processes.

Step3: Note no chromatography examples

Chromatography separates components based on differential affinities for stationary and mobile phases. None of the given examples are chromatography.

Answer:

Filtration: Removing dust particles from the air, Separating coffee grinds from water
Distillation: Preparing gasoline from crude oil, Preparing drinking water from seawater
Chromatography: None
