a. True b. False2. According to the kinetic theory of matter, atoms are in motion…

a. only when heat is added. c. at all times.b. only when heat is removed. d. only when it boils.

3. Thermal energy flows from _______ to _______ objects.a. cold; hot b. hot; cold

Use the diagram to answer questions #4 – #6.

4. ____ Gas5. ____ Liquid6. ____ Solid7. When heat energy is removed, the molecules move…

a. faster and farther apart. c. faster and closer together.

b. slower and farther apart. d. slower and closer together.Use the image below to answer question #8.

8. You decide to have soup and a sandwich for dinner. You get a bowl of soup and set it on the table. But, before you can eat it, someone calls. After your phone call, you pick up the bowl of soup and notice that the table where your bowl was sitting is hot. Why?

a. Heat is circulating through the table at all times.b. Heat was transferred from your bowl of soup to the table.c. Heat is being transferred from the table to your bowl. d. Matter heats and cools sometimes but we don’t

understand why.9. In a house fire, the heat and smoke rise to the ceiling and upper parts of the home first. Why? a. It is blowing toward a window, because hot air finds exits.

b. It is blowing toward the ceiling because hot air fills empty spaces.

c. It is near the ceiling because hot air expands and rises.d. It is near the ceiling because hot air condenses and sinks.

Use the diagram to answer questions #10.

10. When a hot air balloon rises, what are the air particles like outside of the hot air balloon vs. inside the hot air balloon? (There are two answers to this question)

a. Fast particles d. Colder particlesb. Slow particles e. Particles closer togetherc. Hotter particles f. Particles farther apart

11. Ice floats on top of water. Why? a. H2O has faster molecules as a solid than as a liquidb. H2O has denser molecules as warmer water than colder

waterc. H2O when it is colder means that molecules get heavier

and more massive and therefore sink to the bottomd. H2O creates spacing when it freezes so it’s less dense.

You realize that you can see water in all three of its states around you. There are also phases changing through heat transfer. Claim: Describe where you can see the three states of matter when you look at the picture. Evidence: Make a model to show how liquid water molecules change in speed and density when heat energy is being added or taken away. Use a dot to represent each individual molecule.
