ATI TEAS 7 Chemistry (ATI)

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 ...
