| How does evaporation work? | When heated the liquid evaporates leaving the solid behind. |
| How does filtration work? | The holes in the filter paper only lets small particles like water through but not insoluble substances. |
| How does chromatography work? | The water as it rises pulls the ink up, the more soluble ink goes to the top and the less soluble ink stays at the bottom. |
| How does distillation work? | The 2 liquids should have different boiling points, so when you heat it to 100˚C the water evaporates then condenses to form pure water but the other liquid stays. |
