Guide to Understanding the Physical Properties Table Certain abbreviations are used to describe the physical properties of the chemical substances within the Chem Lab. Use this key to help you determine the conventions used throughout the website.
| b.p. |
The boiling point of the compound in degrees Celsius. When presented with boiling points at multiple pressures the given temperature can be assumed to be at one atmosphere, but this may not always be the case. |
| m.p. |
The melting point of the compound in degrees Celsius. When presented with melting points at multiple pressures the given temperature can be assumed to be at one atmosphere, but this may not always be the case. |
| det. |
The compound detonates when heated instead of melting or boiling. A specific temperature at which this occurs may not always be provided. |
| dec. |
The compound decomposes when heated instead of melting or boiling. A specific temperature at which this occurs may not always be provided. |
| def. |
The compound deflagrates when heated instead of melting or boiling. A specific temperature at which this occurs may not always be provided. |
| sublimes |
The compound is converted directly to a gaseous state instead of melting or boiling. |
| den. |
The density of the compound given as mass in grams per one milliliter. This is equivalent to mass in grams per one cubic centimeter. |
| mass |
The molar mass of the compound based on standard atomic weights given as grams per one mole. |
| CAS# |
The Chemical Abstracts Registry Number for the compound. CAS numbers are unique identifiers assigned to chemical substances to help in their identification. For more information about CAS Registry numbers visit the CAS website at http://www.cas.org/expertise/cascontent/registry/regsys.html |
| v.det. |
The velocity of detonation of an explosive given as meters per one second. The v.det. is used as a general yardstick of the “power” of an explosive. A substance can have more than one v.det. depending on the influence of many factors, but generally the highest obtainable figure is listed. |
