The paint evaporated, leaving only clear water in the container.
The water evaporated, leaving only a dry blue solid in the container.
The liquid paint mixture was lighter in color after some water evaporated.
For an investigation a student put 100 mL of water at room temperature into each of three beakers. Then the student added a coin to Beaker R, 3 g of a powdered drink mix to Beaker S, and 10 mL of lamp oil to Beaker T.

Which diagram shows what the student most likely observed in each of the beakers after 5 minutes? (5.5C)
A student stirs 15 grams of each substance listed below into 200 milliliters of water to form four different mixtures.

Salt and water
Gravel and water
Shampoo and water
Sugar and water
