STAAR Matter Review

Study the diagram and carefully read the description below the diagram. Gases have no definite shape or volume. Instead, they take the shape of their container. The particles of a gas spread out within the available space. Which diagram illustrates gas particles?

• Diagram A illustrates gas particles.

• Diagram B illustrates gas particles

• Diagram C illustrates gas particles.

• None of these illustrates gas particles.

In the diagram, State of Matter C is a gas. This means that which of the following statements is true about this state of matter?

• Its particles can move freely throughout the container

• It has a definite volume, but no definite shape

• It has a definite shape and volume

• The particles are rigid and densely placed

A student was asked to compare the masses of four blocks that were all the same size but made of different materials. The student used a balance to compare the masses of two blocks at a time. The student repeated this process three more times with different pairs of blocks and recorded observations. Which list shows the blocks in order from least to greatest mass?

• Blocks N, M, L, P

• Blocks P, M, L, N

• Blocks N, L, M, P

• Blocks P, L, M, N

Some properties of two different samples of matter are below.

Which statement about the samples is most likely correct?

• Sample 1 is glass, sample 2 is clay.

• Sample 1 is iron, sample 2 is sugar.

• Sample 1 is copper, sample 2 is wood.

• Sample 1 is milk, sample 2 is salt.

A student investigated the relative densities of four different liquids. She compared two of the liquids in a beaker. She repeated the process three more times with different liquids and recorded her observations. Which shows the relative density of the four liquids from least dense to most dense?

• Z, W, Y, X

• Y, X, W, Z

• W, X, Y, Z

• Z, W, X, Y

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 liquids, let them settle, and then identify the bottom 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 that increases in volume as water

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