Filtration is when...

• A solvent evaporates to leave a solute behind.

• A Solvent is evaporated then collected and condenses to become a liquid again.

• Sedimentation is sped up by spinning the suspension in circles.

• Sediment sinks to the bottom of a suspension.

• A fluid is passed through a filter to sort particles according to their size.

Distillation is when...
