A) How can be the thermodynamics used in materials engineering? What is the meaning of materials thermodynamics? Give some examples. B) Knowledge of the heat capacities and the entropies of substances and the heats of formation of compounds allows the enthalpy and entropy changes to be evaluated for any process-that is, and C) The enthalpies and the entropies of transformation at the melting point and boiling point of metals can be estimated by the rules of and D) Since consideration of in any isothermal, isobaric process provides the criterion for the equilibrium state of a system can be determined from knowledge of thermochemical properties of the system
