States of Matter Test

When a liquid freezes its particles

• move more rapidly.
• escape from its surface more quickly.
• vibrate faster.
• slow down and become more structured.

This diagram shows particles in three states of matter. What do they all have in common?

• The particles are locked into position.
• The particles in each are in constant motion.
• The particles take the shape of their containers.
• The particles have the same volume in each container.

Which state of matter will take both the volume and shape of the container that holds it?

• gas
• ice
• liquid
• solid

Why does Kool-Aid that is frozen in a popsicle mold tray stay in the shape of a popsicle when it is taken out of the mold?

• The particles vibrate in place but don't have enough energy to move past each other.
• The particles lose enough energy to stop moving completely.
• The particles of the Kool-Aid grow bigger to fill the space in the mold.
• The particles can only slip past one another so they can be poured to fill the mold.

Abby is creating a model to show atoms of solid mercury, liquid mercury, and gaseous mercury. How should her three models differ?

• The size of the atoms should be different depending on the state of matter.
• The mass of the atoms should be different depending on the state of matter.
• The distance of the particles should be different depending on the state of matter
• The identity of the atoms should be different depending on the state of matter.

Frost forms when water vapor changes directly to ice in a process called deposition. If you were to model the water particles before and after deposition, how would they compare?

• Before deposition, the particles vibrate in place; after deposition, they slide by each other.
• Before deposition, the particles slide by each other; after deposition, they vibrate in place.
• Before deposition, the particles vibrate in place; after deposition, they move quickly in all directions.
• Before deposition, the particles move quickly in all directions; after deposition, they vibrate in place.

The diagram below shows how the temperature of water changes as the water changes states. Between which two points does water melt?

• 1 to 2
• 2 to 3
• 3 to 4
• 4 to 5

The diagram below shows how the temperature of water changes as the water changes states. Between which two points does water condense?

• 1 to 2
• 2 to 3
• 3 to 4
• 4 to 5

Molly blows up helium balloons to decorate for the dance. She decides how big or small to make each balloon. Why does the helium she blows into each balloon take up all the space inside the balloon?

• The air particles are easily able to slide past one another.
• Air is a gas and so fills its container, the balloon, completely.
• The air particles increase in size when they have more space.
• There is a strong attraction between the air particles and the balloon.

Katie and Jack are organizing the information they learned about solids, liquids, and gases. They made a Venn diagram. Now they need to fill it in. Which of these statements belongs where all of the states overlap at position 7?

• Particles are spaced far apart.
• Particles are constantly moving.
• Shape depends on the container.
• Sample does not take shape of container.
