Question

mechanical separation
which technique would you use if you wanted to separate coffee grounds from coffee?
distillation
chromatography
magnestism
filtration

Explanation:

Filtration is a separation technique used to separate solid particles from a liquid by passing the mixture through a porous barrier (like a filter paper or coffee filter) that traps the solid while allowing the liquid to pass through. Coffee grounds are insoluble solids, and coffee is the liquid solvent, making filtration the correct method. Distillation separates based on boiling points, chromatography separates components in a mixture based on different movement rates, and magnetism only works for magnetic substances, none of which apply here.

Answer:

filtration
