Create a situation or problem that is related to thermodynamics in chemical engineering and solve the problem. The question must use first and second law of thermodynamics to solve. Energy balance and mass balance are required in the answers. The question may include some apparatus, for example, heat engine, air compressor, piston-cylinder device, turbine, etc.

Design or select a situation. Ideally, something thermodynamic that exists you can observe somehow. Describe it in words and models. Solve it "mathematically" in thermodynamics language and include appropriate assumptions and calculations. Extend and improve your
