I understand that this unit test will include material from unit 5 and 6 and will be on a google form that will be linked near the top of my science gradebook.

• cha!

• did not know that

• I know now!

• huh??

I understand that I have 1 attempt at the test, so i need to make sure to review and be prepared so that I don't need to worry about an AIP.

• Yeeesssss!

Because this phase of matter has molecules that are packed the most tightly, and collide more frequently, sound travels fastest:

• solid

• liquid

• gas

• plasma

Which is a better conductor of heat: air or a copper? Why?

• Copper is a better conductor of heat than air because molecules in a solid are closer together.

• Air is a better conductor of heat because the molecules in a gas are further apart.

• Copper is a better conductor of heat than air because it contains electrons.
