2. States of Matter
Solid
The particles that make up a solid are packed very closely together.

3. States of Matter Types of Solids
Use the Venn diagram to compare the characteristics of amorphous and crystalline solids.

4. States of Matter Liquid
Liquid takes the shape of its container, but its volume does not change.

5. States of Matter
Gas
A gas takes the shape and volume of its container.

6. States of Matter Temperature of a Gas
Why do hot gas particles move faster than cold gas particles?

7. Changes of State Liquid to a Gas
The graph shows the temperature of a small pot of water on a stove set to high heat.

8. Changes of State Melting
Which circle of molecules represents water, and which represents ice?

9. Changes of State Types of Vaporization
Liquid water changes to water vapor by either evaporation or boiling. What
are the types of vaporization occurring in each flask?

10. Changes of State The Changing States of Water
Why does a substance change states?

11. Gas Behavior Temperature and Gas Pressure
When a gas is heated in a closed, rigid container, the particles move faster and collide more often. How would the change in pressure of the gas be shown on each pressure gauge?

12. Gas Behavior Cooling a Balloon
The volume of a gas-filled balloon decreases as temperature decreases and then increases as temperature increases.

13. Gas Behavior Charles’s Law
How would the gas particles and piston look at the different higher temperatures?

14. Gas Behavior Temperature and Gas Volume
The data shown in the table are plotted on the graph.

15. Gas Behavior Boyle’s Law
As weights are added to the top of each piston, the piston moves farther down in the cylinder. Rank the pressure and the volume in each of the cylinders.

16. Gas Behavior Graphing Boyle’s Law
Use the data to make a line graph. What would be a good title for the graph?
