Multi-phase Mixtures

  • Yehuda Klausner

Abstract

In a multi-phase mixture with the phases homogeneously distributed it is convenient to adopt the distinction between the thermodynamic variables introduced by Maxwell (1876):

Mass, volume, strain, energy, entropy, charges, thermodynamic substates, etc. are extensive variables. The magnitude of each variable in the mixture is addable, and is equal to the sum of its magnitudes in the parts of the mixture, or in the phases.

Variables such as density, stress, temperature, thermodynamic tensions, etc. are intensive variables. Their value is independent of the amount of matter in the phase or in any part of the material. Intensive variables are State functions indicating the intensity of the State shared by all the parts of the mixture.
