Question

unit exam - matter and change
what separation technique is illustrated in the picture?
distillation
filtration
evaporation
decantation

Explanation:

The image shows a liquid in an evaporating dish being heated by a flame, which is the setup for evaporation—this technique separates a dissolved solid from a liquid by turning the liquid into vapor, leaving the solid behind. Distillation requires a condenser to collect vapor, filtration uses a filter medium, and decantation is pouring off a liquid without heating.

Answer:

evaporation
