Course Outcomes:

At the end of the course, the student will be able to:

  • Describe basic concepts of thermodynamics such as system, state, state postulate, equilibrium, process, and cycle (L1).

  • Review concepts of temperature, temperature scales, pressure, and absolute and gauge pressure (L1).

  • Define the concept of heat and work and transfer of energy by heat and work (L1).

  • Judge the properties of pure substances (L5).

  • Illustrate the P-v, T-v, and P-T property diagrams and P-v-T surfaces of pure substances (L4).

  • Demonstrate the procedures for determining thermodynamic properties of pure substances from tables of property data  (L3).

  • Describe and apply the ideal-gas equation of state in the solution of typical problems (L2, L3).

  • Identify the first law of thermodynamics as simply a statement of the conservation of energy principle for closed systems and formulate the general energy balance applied to closed systems via heat and work transfer (L1, L6).

  • Apply the first law of thermodynamics to the open systems (L3).

  • Describe the Kelvin–Planck and Clausius statements of the second law of thermodynamics.and assess its thermodynamic applications (L1, L5).
