1. Identify the phase or phases of matter (solids, liquids, and gases) that apply to each statement. More than
one phase of matter may apply to each statement. (Plasma is used once)
a. Molecules do not move around, but vibrate in place __________________
b. Has volume but no particular shape
__________________
c. Flows
__________________ __________________
d. Molecules break free of intermolecular forces __________________
e. Does not have a volume or shape__________________
f. Molecules can move around and switch places, but remain close together__________________
2. Matter has four phases that we experience. List the four phases in order of increasing temperature (lowest
to highest)
3. Put the following terms in order from greatest intermolecular forces, to weakest intermolecular forces:
liquid, gas, solid.
4. Identify the segment of the graph (A, B, C, D, E) in Figure 10.17 where a
phase change is occurring. There could be more than one place. Explain
your reasoning.
