A typical university course structured around Çengel’s curriculum covers the following core modules:
While the First Law identifies energy quantity, the Second Law dictates energy quality and the direction of processes.
Interspersed throughout the math-heavy slides, add peer-instruction questions (e.g., "If an ideal gas expands isothermally, does its internal energy increase, decrease, or stay the same?").
