Question

Which method is best for separating most of a solid from a gas quickly?

distillation
filtration
screening
evaporation

Answer 1

For quickly separating most of a solid from a gas, **filtration** is generally the best method.

Filtration allows you to separate solid particles from a gas (or liquid) by passing the mixture through a filter that captures the solid while allowing the gas to pass through. Distillation is more suited for separating liquids based on boiling points, screening is primarily for sorting based on size, and evaporation is used to separate a solvent from a solute.

So, in this case, the correct answer is **filtration**.
