When people go to the movies, they may be sitting in their seats in the theater, getting concessions in the lobby, or walking outside the building. This scenario can be used as an analogy for the motion and spacing of the particles in each state of matter. If the people at the theater are an analogy for the particles in matter, match each group of people to the state of matter they best represent.

• particles in a solid

• people in the lobby

• particles in a gas

• people walking outside

• particles in a liquid

• people in their seats
