are free to move independently and
collide frequently?
3. Which variable is usually is represented
by the x-axis in a data table?
4. Give 3 equivalent unit labels for volume.
5. Physical changes to matter do not
change what?

6. 6. When CO2(s) changes state directly into a gas
without becoming a liquid, we call
this______________.
7. Which form of matter has both crystalline and
amorphous structures?
8. Plant leaves lose water through evaporation –
physical or chemical? Why?
9. Proteins are made from amino acids –
physical or chemical? Why?

7. 12. What method would you use to find
the volume of a block of wood?
13. What are 3 equivalent formulas for
finding the volume of a cube?
14. What determines the state of matter a
substance is in?
15. When will a substance float in water?
16. What is the vocabulary word for
finding the volume of an irregularly
shaped object?

8. A substance’s density is the measure of
the mass of material within a certain
volume. (amnt of space taken up)
The mass (amnt of particles) is affected by how
tightly packed the molecules are within
the space.
