A student measured out 10 mL of four clear liquids and added one drop of a different-colored dye to each liquid. One of the liquids was water. The student then carefully poured each liquid into a graduated cylinder and let the mixture settle for 30 minutes. The student observed that the liquids had separated into layers, as shown in the diagram.

Which of these procedures would help the student identify the layer of water?

• Stir the liquid, let them settle, and then identify the layer as water

• Drop a piece of ice into the graduated cylinder, let the ice settle, and then identify the layer just above the ice as water

• Add water to the graduated cylinder, let the mixture settle, and then identify the layer just above the ice as water

• Carefully pour each layer into separate plastic containers, place containers in a freezer, and then identify the liquid that takes the longest to freeze as water
