- Material properties (thermodynamics)
The thermodynamic properties of materials are intensive thermodynamic parameters which are specific to a given material. Each is directly related to a second order differential of a thermodynamic potential. Examples for a simple 1-component system are:
- Isothermal compressibility
- Adiabatic compressibility
- Specific heat (Note - the extensive analog is the heat capacity)
- Specific heat at constant pressure
- Specific heat at constant volume
- Coefficient of thermal expansion
For a single component system, only three second derivatives are needed in order to derive all others, and so only three material properties are needed to derive all others. For a single component system, the "standard" three parameters are the isothermal compressibility βT, the specific heat at constant pressure cP, and the coefficient of thermal expansion α.
For example, the following equations are true:
The three "standard" properties are in fact the three possible second derivatives of the Gibbs free energy with respect to temperature and pressure.
