​STATES OF Matter

By Keyshawn Powell

Open Ended

An ice cube is left outside on a warm day.

Question:
Describe what happens to the ice cube and explain what heat does to the particles.

Multiple Choice

A student leaves a bottle of juice in a car overnight during winter. In the morning, the juice is frozen.

Which statement BEST explains what happened?

• Heat was added, causing the particles to move faster and spread apart

• Heat was removed, causing the particles to slow down and move closer together

• The juice changed into a new substance

• The particles disappeared when it got cold

Multiple Choice

When water changes from a liquid to a gas, what happens to the particles?

• They stop moving

• They move closer together

• They spread farther apart and move faster

• They change into a new substance

Multiple Choice

Ice cream begins to melt on a hot sidewalk.

What is the MOST likely cause of this change?

• A decrease in temperature

• An increase in temperature

• A change in mass

• A chemical reaction

A student puts a cup of water in the freezer. After a few hours, the water turns into ice.

Question:
Explain why the water changed into ice. Use temperature and particle movement in your answer.

Multiple Choice

A student heats soup on the stove. After boiling, there is less liquid in the pot.

What happened to the missing liquid?

• It was destroyed

• It turned into water vapor

• It soaked into the pot

• It changed into a solid

Multiple Choice

After a rainstorm, a puddle forms on the playground. That night, the temperature drops below freezing.

What will MOST likely happen to the puddle, and why?

• It will evaporate because the particles move faster

• It will freeze because the particles slow down and move closer together

• It will turn into gas because heat is removed

• It will disappear because the water is absorbed

Multiple Choice

Which description BEST matches a gas?

• Particles are close together and vibrate

• Particles are close together and slide past each other

• Particles are far apart and move quickly in all directions

• Particles are packed tightly and do not move

Multiple Choice

A model shows particles moving faster in State B than in State A.

What MOST likely caused the change?

• Heat was removed

• Heat was added

• The substance became heavier

• A chemical reaction occurred

After it rains, a puddle disappears on a hot day.

Question:
Where did the water go? Explain using particle movement.
