any change that results in the formation of a new chemical substance.
chromatography
parts of a mixture are separated based on the ability of each dissolved component to travel through materials at different speeds.
combustibility

condensation point
the temperature at which a gas turns into a liquid at standard pressure.
crystallization
the separation of a pure solid substance from a solution containing the dissolved substance.
density
the amount of mass per unit volume.
deposition
when a gas changes directly into a solid without going through the liquid phase.
distillation
the process that separates homogenous mixtures based on the different boiling points of the substances.
enthalpy
