EMS 164 - Homework 1 Solutions 1. Define in your own words the following terms: enthalpy, entropy, free energy, eutectic. Give examples of systems composed of one phase and two phases. For the latter, indicate the two phases (hint: you may consider some microstructures in earlier classes such as E45 and EMS162) ( 8 Points) Enthalpy: (Either of them, 1 Point) A thermodynamic function of a system, equivalent to the sum of the internal energy of the system plus the product of its volume multiplied by the pressure exerted on it by its surroundings. Thermodynamic potential of a system, which can be used to calculate the heat transfer during a quasistatic process taking place in a closed thermodynamic system under constant pressure. ΔH=E+PV where E is the internal energy of the system Entropy: (Either of them, 1 Point) A measure of the disorder or randomness in a closed system. The state function which, when multiplied by a reference temperature, can be understood as a measure of the amount of energy in a physical system that cannot be used to do thermodynamic work. Free energy:
