Please contact Savvas Learning Company for product support. The term standard state is used to describe a reference state for substances, and is a help in thermodynamical calculations (as enthalpy, entropy and Gibbs free energy calculations). Other rocks can be defined by relative abundances of key (essential) minerals; a granite is defined by proportions of quartz, alkali feldspar, and plagioclase feldspar. The superscript degree symbol () indicates that substances are in their standard states. Aluminum comes in heat treatable and nonheat treatable alloys.
