An introduction to concepts and principles in chemical and process thermodynamics. This course includes the 1st and 2nd Laws, equilibrium and reversibility, ideal gas process calculations and refrigeration and heat pump cycles.

Thermodynamics is a core subject for chemical and process engineering. Its principles are used in fluid mechanics, reaction engineering, heat and mass transfer, separation processes and process energy balances. This course emphasises the development of these general principles including the 1st and 2nd Laws and the application of these to energy balances. This course will also reinforce mathematical concepts (such as partial derivatives) by linking them to physical phenomenon related to thermodynamics.

Course Topics

• Internal energy, heat, work, state functions and the 1st law of thermodynamics
• Properties of Ideal gases and PVT behaviour of fluids
• Application of partial derivatives and integral calculus to thermodynamics
• Reversibility and equilibrium
• Ideal gas processes
• Phase diagrams and the Phase rule
• Enthalpy and its use in energy balances including reactions and phase changes
• Thermodynamics of ideal mixtures
• Steam tables and others sources of thermodynamic data
• The 2nd Law, heat engines, Entropy and Gibbs energy

Learning Outcomes

  • Understand the concept of energy storage and energy transfer
  • Knowledge of the 1st Law of thermodynamics and its limits
  • Be capable in using and describing partial derivatives in thermodynamics
  • Able to perform ideal gas process calculations and understand the limits of application
  • Be able to describe reversibility and equilibrium
  • Understand phase diagrams, the phase rule and phase transition
  • Able to use and apply energy balances to complex systems
  • Understand reference states and be capable of obtaining thermodynamic data  
  • Knowledge of the 2nd Law of thermodynamics and basic understanding of entropy and entropy changes
  • Capable of performing heat engine, refrigeration and steam turbine calculations


Subject to the approval of the Dean of Engineering and Forestry.
