Which statement BEST describes what happens as water changes from one state to another?
As water is cooled, it freezes and changes from a solid to a liquid.
As water is cooled, it condenses and changes from a gas to a liquid.

A student poured equal amounts of water and cooking oil into a jar. The student placed a lid on the jar and shook the mixture for five seconds and then let the jar sit for ten minutes. The results of this investigation are shown.
Which conclusion best compares a property of cooking oil and water shown in this investigation?
Cooking oil is less dense than water.
Water is less dense than cooking oil.
Water dissolves in cooking oil.
Cooking oil dissolves in water.
Students observe some objects on a lab tray. The students will classify the objects based on physical properties common to all of the objects.
Based on their common properties, how should these objects be classified?
Insulate thermal energy, Bendable, Attract to magnets
Soluble in water, Attract to magnets, Conduct thermal energy
Conduct electrical energy, Bendable, Soluble in water
Conduct thermal energy, Conduct electrical energy, Not soluble in water
A table of different properties of four samples of matter is shown.
Which conclusion can be made about the samples based on the table?
Sample 1 is made of plastic.
Sample 2 is made of metal.
Sample 3 is attracted to magnets.
Sample 4 is less dense than water.
A student compares the physical properties of the four objects shown.
Which of these physical properties do all four objects have in common?
They all have the same physical state and conduct electricity.
They all conduct electricity and attract the same metal objects.
They all attract the same metal objects and are not soluble in water.
They all are not soluble in water and have the same physical state.
A group of students is given four small cubes of the same size and instructed to place them in a beaker of water. One cube floats to the surface of the water. Two of the cubes float in the middle of the beaker under the surface of the water. The last cube sinks to the bottom of the beaker.
Which conclusion is best supported by what the students observed?
Two of the four cubes are soluble in water.
All four cubes have different masses.
Each cube is made of a different type of solid material.
One of the cubes is more dense than the other three.
Students investigate the physical properties of some substances. They draw a table to show how the substances can be grouped. The students need to complete the table with column headings.
Which column headings should the students use for their table?
A student filled each of four beakers with 100 mL of water at 25 °C. The student added an equal amount of a different substance to each of the beakers of water.
Based on the student’s observations in the table, how many of the substances did NOT dissolve in the water?
1 substance
2 substances
3 substances
4 substances
A student wants to classify four different objects based on physical properties. The student uses the questions shown in the table to test each object.
Which statement correctly identifies two of the materials based on the classification of properties in the table?
Material 1 is a rubber ball. Material 2 is a piece of cardboard.
Material 2 is an aluminum washer. Material 3 is a copper wire.
Material 3 is a piece of cardboard. Material 4 is an aluminum washer.
Material 1 is a copper wire. Material 4 is a rubber ball.
The pictures show tools that can be used for separating mixtures.
Which mixture is paired with the best tool for separating the materials?
salt and pepper | Tweezers
pieces of cork and pebbles | Beaker of water
safety pins and iron nails | Magnet
Sand and iron filings | Colander
Students conduct an investigation with breakfast cereal. The first four steps of the students’ investigation are in the table shown.
The students are trying to determine the presence of which substance in the cereal?

A student mixes a sample of stones with a sample of table salt. The mass and volume of the samples were determined before mixing the samples. The mass and volume of each sample is shown.
Which statement is true about the mixture?
The mass of the mixture is 85 grams.
The mass of the mixture is 60 milliliters.
The volume of the mixture is 60 grams.

A student heats 250 milliliters of water in a cup to approximately to 50°C and adds 6 grams of salt. The mixture of salt and water is then stirred for 15 seconds.
Which results will the student MOST LIKELY observe the mixture has been stirred for 15 seconds?
Select TWO correct answers
The salt will dissolve.
The salt will sink to the bottom of the cup.
The water will remain clear.
The salt will float on the water.
The water will change from clear to opaque white.
A student pours 14 grams of sugar into a jar filled with 500 milliliters of water. The student thoroughly stirs the sugar and water to make a solution.

The sugar breaks down to form a new substance in the solution.
The sugar changes water into a new substance in the solution.
The sugar floats on the surface of the water in the solution.

A student prepared a snack that consisted of grapes, pecans, 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 nuts.
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.
