Normal boiling point definition chemistry

The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into a vapor. The boiling point of a liquid varies depending upon the surrounding environmental pressure. A liquid in a partial vacuum, i.e., under a lower press… Web14 de nov. de 2004 · The basic method to estimate boiling point is Group Contibution (Additivity) method. This method determine each Functional group's (FG's) factor and make summation. For example, normal alkane compounds, the boiling point will increase 30.494K if CH2 group increase one. Joback determined these factors with statistically.
