WebbA thermodynamic database can be used to predict these properties and also show the effects of non-equilibrium solidification. The results from these predictions can be used to eliminate candidate solder alloys for which the calculation revealed unsuitable freezing temperature and range from further testing. WebbThermodynamic Data Thermodynamic data for individual species are necessary for performing equilibrium chemistry and finite-rate chemical kinetics calculations. These data typically provide the thermodynamic properties (enthalpy, entropy, and specific heat) of a species as a function of temperature.
