Catalog Course Description
Fundamental concepts and mathematical tools ; thermal equilibrium; Zeroth Law and definition of temperature; equations of state; First and Second Laws; thermodynamic potentials (enthalpy, Helmholtz, Gibbs) and the Maxwell relations; first order phase transitions; critical phenomena; Third Law, negative temperatures; introduction to statistical mechanics.
Course Learning Outcomes:
| 1. | State and explain general concepts used in thermodynamics including the system and its surroundings, mechanisms of energy transfer; state versus path function. |
|---|---|
| 2. | Interpret the basic assumptions of the ideal gas law and illustrate how the van der Waals equation of state rectifies these assumptions to lead to a gas <-> liquid phase transition behavior and the critical point. |
| 3. | Using published data, such as heat capacity, calculate the internal energy, enthalpy changes of a system with respect to a reference state. |
| 4. | Apply the first law of thermodynamics by performing a detailed balance of energy transfer for a variety of real systems involving thermal energy, calculate efficiency in energy conversion |
| 5. | Define second law of thermodynamics and using published data calculate the entropy change of a system and surroundings |
| 6. | Define and calculate the Gibbs and Helmholtz free energy changes in various systems using Maxwell's relations, write the differential forms of state functions |
| 7. | Define chemical potential and relate it to change in Gibbs energy and identify reversibility and spontaneity in changes towards equilibrium. |
| 8. | Describe the physical, structural, and thermodynamic properties of equilibrium phases and phase transformations in single and two-component systems |
| 9. | Determine the changes in thermodynamic properties in ideal, non-ideal, dilute, and in regular solutions |
| 10. | Draw P-V and T-V diagram of pure substances, determine the phase of a substance at different conditions |
| 11. | Calculate the activities and activity coefficients for real solutions |
| 12. | Apply the Lever Rule to determine the phase composition in a multi-phase field; |
| 13. | Define the ideal thermodynamic cycles for gas and gas-vapor systems and calculate the thermal efficiency |
Course Objective
To equip the students with a basic understanding of equilibrium, both from a macroscopic and a microscopic viewpoint, so that they can (i) perform the energy balance for a system and analyze the energy transfer processes in the system; (ii) interrelate various thermodynamic functions so that hard-to-measure properties may be determined through the measurable ones; (iii) develop a basic understanding of phase behavior.
