-When thermal energy is applied to a substance, let's say glass, the energy between the bonds increases and the result is an extension of the bond length.  This can result in two types of expansion, linear and volumetric.
-Each type of glass that is varied upon its molecular composition will result in a different COE.  Although one could create two substances that have identical thermal expansion profiles, glass is typicaly catagorized via it's COE.
