A student drew diagrams to show the particles in solids, liquids and gases. She needs to label the diagrams.

2. What is the correct order for the labels of the diagrams she drew?

• solid, liquid, gas

• liquid, solid, gas

• liquid, gas, solid

• solid, gas, liquid

Based on the observations, students would classify some materials as solids because _________________.

They have a fixed shape and volume. They change shape and expand to fill different containers. They take the shape of the container, but has a fixed volume. They have a fixed shape, but expand to fill different containers.

A student measured the volume of a certain type of matter in three different containers shown below.

• They have a fixed shape and volume.

• They change shape and expand to fill different containers.

• They take the shape of the container, but has a fixed volume.

• They have a fixed shape, but expand to fill different containers.

A student measured the volume of a certain type of matter in three different containers shown below.

What is the best conclusion she can make from her observation?

• The volume of the matter is greater in the graduated cylinder.

• The matter she is measuring is a gas.

• The matter she is measuring is a liquid.

• The volume of the matter is greater in the beaker.

Iron is attracted to a magnet. Sulfur is not attracted to a magnet. The diagram below shows what happens when a magnet is placed into a mixture of sulfur powder and iron.

What is the best claim that can be made about mixtures form the results of this investigation?

• The magnetic property of iron does not change when it is mixed.

• The magnetic property of sulfur changes when mixed with iron.

• The properties of matter change when different types of matter are mixed.

• The mass of matter does not change when mixed with other matter

A student poured 2 grams of salt into a beaker containing 10 grams of clear water. Below are the results of his investigation.

The mass of the mixture was 12 grams.

The water was still clear.

He could no longer see the salt.

Which of the following best explains why he could not see the salt?

• In a solution the substances cannot be distinguished as separate substances.

• In a mixture the mass of the substances does not change.

• In a solution the properties of a substance do not change.

• In a mixture the substances cannot be separated based on their properties.

The picture below shows a student pouring milk on his cereal.

Which of the following best explains what he is making?

• He is making a solution because he is pouring a liquid.

• He is making a mixture because the substances can be separated.

• He is making a mixture because the properties change.

What claim is best supported by the data in this table?

• Solids and liquids cannot be combined into a mixture.

• Vinegar and oil separate after they have been combined into a mixture.

• Some of the mass of the water escape as gas mixed with sugar.

• When two substances are mixed together, their total mass does not change.

Which property of a mixture does this diagram best illustrate?

• Solids melt when combined with liquids in a mixture.

• Gases can be released when some substances are combined.

• Mixtures can be separated back into their different substances.

• The mass of a mixture is not the same as the combined mass of the substance.
