UNDERSTANDING STATES OF MATTER
Matter is made up of microscopic particles that move different speeds depending on the
energy they are exposed to. We measure this energy as temperature. The molecules
can move either quickly and randomly or hardly at all.
When the energy is high, matter take the form of a gas, in which molecules are moving
about quickly and are far apart. Gases have no fixed form. Molecules are free to move
at random past each other, and they tend to fill any container that holds them. If a gas is
not contained, its molecules will disperse.
