Glossary
This glossary will give you definitions of some commonly used vocabulary on this Chemistry site.
Absolute Zero: A state at which there is no kinetic energy. It is usually defined as Zero Kelvin, which equals to about -459º Fahrenheit or -273º Celsius.
Atom: This is the smallest particle of an element that retains the chemical properties of the element. Atoms are electrically neutral, with a positively charged nucleus that binds one or more electrons in motion around it.
Boiling Point: The temperature at which the vapor pressure f a liquid is equal to the external pressure on the liquid. The standard boiling point is the temperature at which the vapor pressure of a liquid equals standard pressure.
Chromatography: Chromatography is a method for separating mixtures based on differences in the speed at which they move.
Compound: A material formed from elements chemically combined in definite proportions by mass.
Distillation: A technique for separating components of a mixture on the basis of differing boiling points. The mixture is heated, vaporizing some of the components. The vapor is collected and condensed to isolate the components with the lowest boiling points.
