Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. Which state of matter has particles that are tightly packed and vibrate in fixed positions?
Liquid
Solid
Gas
Plasma
2. What happens to the kinetic energy of particles as a substance is heated?
Decreases
Increases
Remains constant
Becomes zero
3. The particle model states that all matter is made up of tiny, constantly moving .
4. In a gas, particles have a large amount of energy and are far apart.
5. The change of state from liquid to gas is called .
6. Particles in a solid are able to move freely past each other.
True
False
7. Adding energy to a substance always causes its temperature to increase.
True
False
8. Describe the arrangement and movement of particles in a liquid.
9. Explain how the particle model accounts for the compressibility of gases versus liquids.
10. Observe the diagram below showing the particle arrangement in different states of matter. Label each diagram with the correct state of matter (Solid, Liquid, or Gas).
