This law introduces the concept of entropy ($S$) and dictates the direction of natural processes. While the First Law says energy is conserved, the Second Law says the quality of energy is always degrading. It states that in any energy conversion process, the total entropy of an isolated system always increases (or remains constant in a reversible process). This is why you cannot build a perfectly efficient heat engine; some energy is always lost as lower-temperature waste heat. This law is described by the Clausius inequality: [ \oint \frac\delta QT \le 0 ]

: Unique to Malić’s work is the inclusion of the history and development of thermodynamics, providing a broader context for why certain principles were established. 4. Critical Assessment termodinamika i termotehnika pdf work
