Abstract:

We discussed the physical meaning of the molecular partition function, and the role of both the molecular partition function and the partition function of the system in the calculation of the thermodynamic properties.It was shown that the molecular partition function is neither an extensive property nor an intensive one, but only a tie to connect the thermodynamic properties with the microscopic information of the system.

Key words: Molecular partition function, Canonical partition function, Thermodynamic function, Intensive property, Extensive property
