Solids, Liquids, and Gases: Moving Particles This diagram shows what happens to particles during changes of state. This is not what you would actually see, but the diagram helps you understand what is
actually happening. Focus on how much the particles move. Change of State Molecules moving faster and faster More and more heat absorbed
Study the diagram and answer the questions below. 1. What happens to the speed of molecules as they absorb heat?
2. In which state have the particles absorbed the most heat?
3. Which particles show the least amount of motion? >
4. In which state do the particles occupy the greatest amount of space?

Match the correct letter with the description.
1. the temperature at which a liquid changes state into a solid
2. the temperature at which a solid changes state into a liquid
state of matter
change of state
3. a liquid slowing changing into a gas 4. any of the forms matter can exist in 5. a gas turning to a liquid 6. the temperature at which a liquid changes state into a gas 7. the temperature stays constant during this even though heat is being added or removed 8. cooling causes particles to get closer together and materials do this
9. sidewalks have cracks between pieces because many solids do this when they are heated
10. Explain why the temperature of water stays the same for a while once it starts boiling.
