A student prepared a snack that consisted of grapes, pecan, and strawberries sprinkled with white powdered sugar. The student stored the snack in a refrigerator. An hour later the student observed that the powdered sugar could no longer be seen but the fruit and nuts had not changed in appearance. What MOST LIKELY happened to the sugar in the mixture?

• The sugar evaporated at the lower temperature in the refrigerator without causing any changes to the fruit and pecans.

• The sugar was more dense than the other foods in the mixture, so it settled to the bottom of the container.

• The sugar dissolved in the moisture on the fruit.

• The sugar absorbed energy from the nuts and melted into a colorless liquid.

• They all have the same physical state.

• They all conduct electricity.

• They all are attracted to magnets.

• They all are not soluble in water.

• They are all insulators.

A student poured equal amounts of water and cooking oil into a jar. The student placed a lid on the jar, shook the mixture for five seconds, and then let the jar sit for ten minutes. The results of this investigation are shown. Which conclusions best compare a property of cooking oil and water shown in this investigation? Choose TWO correct answers.

• Cooking oil is less dense than water.

• Water is less dense than cooking oil.

• Water dissolves in cooking oil.

• Cooking oil dissolves in water.

A student is conducting an investigation using different objects in water to compare density. Each object is placed in a beaker that contains the same amount of water. Which statements are supported by this investigation?

Select TWO correct answers.

• A feather can be classified with Object 3 because the feather has a density that is greater than liquid water.

• A concrete block can be classified with Object 3 because both have a density that is greater than liquid water.

• A coin can be classified with Object 1 because both have a density equal to liquid water.

• A glass marble can be classified with Object 2 because the glass marble has a density that is less than liquid water.

• A wooden toothpick can be classified with Object 2 because they both have a density that is less than liquid water.
