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 near the ceiling to find a window, because hot air finds exits.b. It is near 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.

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 three answers to this question)

a. Faster particlesb. Slower particlesc. Hotter particlesd. Colder particlese. Particles closer togetherf. Particles farther apart.

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

a. Faster particlesb. Slower particlesc. Hotter particles

d. Colder particlese. Particles closer togetherf. Particles farther apart.

12. 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.

In the boxes below, write the correct word which describes the phase change.

Phenomena: You visit Yellowstone National Park. One morning, you see this beautiful scene.

You realize that you can see water in all three of its states around you. There are also phases changing through heat transfer. Identify where you see each phase.
